feat: add multi-feature batching for coding agents

Enable the orchestrator to assign 1-3 features per coding agent subprocess,
selected via dependency chain extension + same-category fill. This reduces
cold-start overhead and leverages shared context across related features.

Orchestrator (parallel_orchestrator.py):
- Add batch tracking: _batch_features and _feature_to_primary data structures
- Add build_feature_batches() with dependency chain + category fill algorithm
- Add start_feature_batch() and _spawn_coding_agent_batch() methods
- Update _on_agent_complete() for batch cleanup across all features
- Update stop_feature() with _feature_to_primary lookup
- Update get_ready_features() to exclude all batch feature IDs
- Update main loop to build batches then spawn per available slot

CLI and agent layer:
- Add --feature-ids (comma-separated) and --batch-size CLI args
- Add feature_ids parameter to run_autonomous_agent() with batch prompt selection
- Add get_batch_feature_prompt() with sequential workflow instructions

WebSocket layer (server/websocket.py):
- Add BATCH_CODING_AGENT_START_PATTERN and BATCH_FEATURES_COMPLETE_PATTERN
- Add _handle_batch_agent_start() and _handle_batch_agent_complete() methods
- Add featureIds field to all agent_update messages
- Track current_feature_id updates as agent moves through batch

Frontend (React UI):
- Add featureIds to ActiveAgent and WSAgentUpdateMessage types
- Update KanbanColumn and DependencyGraph agent-feature maps for batch
- Update AgentCard to show "Batch: #X, #Y, #Z" with active feature highlight
- Add "Features per Agent" segmented control (1-3) in SettingsModal

Settings integration (full stack):
- Add batch_size to schemas, settings router, agent router, process manager
- Default batch_size=3, user-configurable 1-3 via settings UI
- batch_size=1 is functionally identical to pre-batching behavior

-| "No data to test with" | Skip | Create test data or build data entry flow |
-| "Feature X needs to be done first" | Skip | Build feature X as part of this feature |

 ### STEP 5.5: MANDATORY VERIFICATION CHECKLIST (BEFORE MARKING ANY TEST PASSING)
 
-**You MUST complete ALL of these checks before marking any feature as "passes": true**
+**Complete ALL applicable checks before marking any feature as passing:**
 
-#### Security Verification (for protected features)
-
-- [ ] Feature respects user role permissions
-- [ ] Unauthenticated access is blocked (redirects to login)
-- [ ] API endpoint checks authorization (returns 401/403 appropriately)
-- [ ] Cannot access other users' data by manipulating URLs
-
-#### Real Data Verification (CRITICAL - NO MOCK DATA)
-
-- [ ] Created unique test data via UI (e.g., "TEST_12345_VERIFY_ME")
-- [ ] Verified the EXACT data I created appears in UI
-- [ ] Refreshed page - data persists (proves database storage)
-- [ ] Deleted the test data - verified it's gone everywhere
-- [ ] NO unexplained data appeared (would indicate mock data)
-- [ ] Dashboard/counts reflect real numbers after my changes
-- [ ] **Ran extended mock data grep (STEP 5.6) - no hits in src/ (excluding tests)**
-- [ ] **Verified no globalThis, devStore, or dev-store patterns**
-- [ ] **Server restart test passed (STEP 5.7) - data persists across restart**
-
-#### Navigation Verification
-
-- [ ] All buttons on this page link to existing routes
-- [ ] No 404 errors when clicking any interactive element
-- [ ] Back button returns to correct previous page
-- [ ] Related links (edit, view, delete) have correct IDs in URLs
-
-#### Integration Verification
-
-- [ ] Console shows ZERO JavaScript errors
-- [ ] Network tab shows successful API calls (no 500s)
-- [ ] Data returned from API matches what UI displays
-- [ ] Loading states appeared during API calls
-- [ ] Error states handle failures gracefully
+- **Security:** Feature respects role permissions; unauthenticated access blocked; API checks auth (401/403); no cross-user data leaks via URL manipulation
+- **Real Data:** Create unique test data via UI, verify it appears, refresh to confirm persistence, delete and verify removal. No unexplained data (indicates mocks). Dashboard counts reflect real numbers
+- **Mock Data Grep:** Run STEP 5.6 grep checks - no hits in src/ (excluding tests). No globalThis, devStore, or dev-store patterns
+- **Server Restart:** For data features, run STEP 5.7 - data persists across server restart
+- **Navigation:** All buttons link to existing routes, no 404s, back button works, edit/view/delete links have correct IDs
+- **Integration:** Zero JS console errors, no 500s in network tab, API data matches UI, loading/error states work
 
 ### STEP 5.6: MOCK DATA DETECTION (Before marking passing)
 
-**Run ALL these grep checks. Any hits in src/ (excluding test files) require investigation:**
-
-```bash
-# Common exclusions for test files
-EXCLUDE="--exclude=*.test.* --exclude=*.spec.* --exclude=*__test__* --exclude=*__mocks__*"
-
-# 1. In-memory storage patterns (CRITICAL - catches dev-store)
-grep -r "globalThis\." --include="*.ts" --include="*.tsx" --include="*.js" $EXCLUDE src/
-grep -r "dev-store\|devStore\|DevStore\|mock-db\|mockDb" --include="*.ts" --include="*.tsx" --include="*.js" $EXCLUDE src/
-
-# 2. Mock data variables
-grep -r "mockData\|fakeData\|sampleData\|dummyData\|testData" --include="*.ts" --include="*.tsx" --include="*.js" $EXCLUDE src/
-
-# 3. TODO/incomplete markers
-grep -r "TODO.*real\|TODO.*database\|TODO.*API\|STUB\|MOCK" --include="*.ts" --include="*.tsx" --include="*.js" $EXCLUDE src/
-
-# 4. Development-only conditionals
-grep -r "isDevelopment\|isDev\|process\.env\.NODE_ENV.*development" --include="*.ts" --include="*.tsx" --include="*.js" $EXCLUDE src/
-
-# 5. In-memory collections as data stores
-grep -r "new Map\(\)\|new Set\(\)" --include="*.ts" --include="*.tsx" --include="*.js" $EXCLUDE src/ 2>/dev/null
-```
-
-**Rule:** If ANY grep returns results in production code → investigate → FIX before marking passing.
-
-**Runtime verification:**
-1. Create unique data (e.g., "TEST_12345") → verify in UI → delete → verify gone
-2. Check database directly - all displayed data must come from real DB queries
-3. If unexplained data appears, it's mock data - fix before marking passing.
+Before marking a feature passing, grep for mock/placeholder data patterns in src/ (excluding test files): `globalThis`, `devStore`, `dev-store`, `mockDb`, `mockData`, `fakeData`, `sampleData`, `dummyData`, `testData`, `TODO.*real`, `TODO.*database`, `STUB`, `MOCK`, `isDevelopment`, `isDev`. Any hits in production code must be investigated and fixed. Also create unique test data (e.g., "TEST_12345"), verify it appears in UI, then delete and confirm removal - unexplained data indicates mock implementations.
 
 ### STEP 5.7: SERVER RESTART PERSISTENCE TEST (MANDATORY for data features)
 
-**When required:** Any feature involving CRUD operations or data persistence.
-
-**This test is NON-NEGOTIABLE. It catches in-memory storage implementations that pass all other tests.**
-
-**Steps:**
-
-1. Create unique test data via UI or API (e.g., item named "RESTART_TEST_12345")
-2. Verify data appears in UI and API response
-
-3. **STOP the server completely:**
-   ```bash
-   # Kill by port (safer - only kills the dev server, not VS Code/Claude Code/etc.)
-   # Unix/macOS:
-   lsof -ti :${PORT:-3000} | xargs kill -TERM 2>/dev/null || true
-   sleep 3
-   lsof -ti :${PORT:-3000} | xargs kill -9 2>/dev/null || true
-   sleep 2
-
-   # Windows alternative (use if lsof not available):
-   # netstat -ano | findstr :${PORT:-3000} | findstr LISTENING
-   # taskkill /F /PID <pid_from_above> 2>nul
-
-   # Verify server is stopped
-   if lsof -ti :${PORT:-3000} > /dev/null 2>&1; then
-     echo "ERROR: Server still running on port ${PORT:-3000}!"
-     exit 1
-   fi
-   ```
-
-4. **RESTART the server:**
-   ```bash
-   ./init.sh &
-   sleep 15  # Allow server to fully start
-   # Verify server is responding
-   if ! curl -f http://localhost:${PORT:-3000}/api/health && ! curl -f http://localhost:${PORT:-3000}; then
-     echo "ERROR: Server failed to start after restart"
-     exit 1
-   fi
-   ```
-
-5. **Query for test data - it MUST still exist**
-   - Via UI: Navigate to data location, verify data appears
-   - Via API: `curl http://localhost:${PORT:-3000}/api/items` - verify data in response
-
-6. **If data is GONE:** Implementation uses in-memory storage → CRITICAL FAIL
-   - Run all grep commands from STEP 5.6 to identify the mock pattern
-   - You MUST fix the in-memory storage implementation before proceeding
-   - Replace in-memory storage with real database queries
-
-7. **Clean up test data** after successful verification
-
-**Why this test exists:** In-memory stores like `globalThis.devStore` pass all other tests because data persists during a single server run. Only a full server restart reveals this bug. Skipping this step WILL allow dev-store implementations to slip through.
-
-**YOLO Mode Note:** Even in YOLO mode, this verification is MANDATORY for data features. Use curl instead of browser automation.
+For any feature involving CRUD or data persistence: create unique test data (e.g., "RESTART_TEST_12345"), verify it exists, then fully stop and restart the dev server. After restart, verify the test data still exists. If data is gone, the implementation uses in-memory storage -- run STEP 5.6 greps, find the mock pattern, and replace with real database queries. Clean up test data after verification. This test catches in-memory stores like `globalThis.devStore` that pass all other tests but lose data on restart.

-## 1. UI Theme Customization
-
-### Overview
-
-The UI has been customized from the default **neobrutalism** style to a clean **Twitter/Supabase-style** design.
-
-**Design Changes:**
-- No shadows
-- Thin borders (1px)
-- Rounded corners (1.3rem base)
-- Blue accent color (Twitter blue)
-- Clean typography (Open Sans)
-
-### Modified Files
-
-#### `ui/src/styles/custom-theme.css`
-
-**Purpose:** Main theme override file that replaces neo design with clean Twitter style.
-
-**Key Changes:**
-- All `--shadow-neo-*` variables set to `none`
-- All status colors (`pending`, `progress`, `done`) use Twitter blue
-- Rounded corners: `--radius-neo-lg: 1.3rem`
-- Font: Open Sans
-- Removed all transform effects on hover
-- Dark mode with proper contrast
-
-**CSS Variables (Light Mode):**
-```css
---color-neo-accent: oklch(0.6723 0.1606 244.9955);  /* Twitter blue */
---color-neo-pending: oklch(0.6723 0.1606 244.9955);
---color-neo-progress: oklch(0.6723 0.1606 244.9955);
---color-neo-done: oklch(0.6723 0.1606 244.9955);
-```
-
-**CSS Variables (Dark Mode):**
-```css
---color-neo-bg: oklch(0.08 0 0);
---color-neo-card: oklch(0.16 0.005 250);
---color-neo-border: oklch(0.30 0 0);
-```
-
-**How to preserve:** This file should NOT be overwritten. It loads after `globals.css` and overrides it.
-
----
-
-#### `ui/src/components/KanbanColumn.tsx`
-
-**Purpose:** Modified to support themeable kanban columns without inline styles.
-
-**Changes:**
-
-1. **colorMap changed from inline colors to CSS classes:**
-```tsx
-// BEFORE (original):
-const colorMap = {
-  pending: 'var(--color-neo-pending)',
-  progress: 'var(--color-neo-progress)',
-  done: 'var(--color-neo-done)',
-}
-
-// AFTER (customized):
-const colorMap = {
-  pending: 'kanban-header-pending',
-  progress: 'kanban-header-progress',
-  done: 'kanban-header-done',
-}
-```
-
-2. **Column div uses CSS class instead of inline style:**
-```tsx
-// BEFORE:
-<div className="neo-card overflow-hidden" style={{ borderColor: colorMap[color] }}>
-
-// AFTER:
-<div className={`neo-card overflow-hidden kanban-column ${colorMap[color]}`}>
-```
-
-3. **Header div simplified (removed duplicate color class):**
-```tsx
-// BEFORE:
-<div className={`... ${colorMap[color]}`} style={{ backgroundColor: colorMap[color] }}>
-
-// AFTER:
-<div className="kanban-header px-4 py-3 border-b border-[var(--color-neo-border)]">
-```
-
-4. **Title text color:**
-```tsx
-// BEFORE:
-text-[var(--color-neo-text-on-bright)]
-
-// AFTER:
-text-[var(--color-neo-text)]
-```

-## 2. Playwright Browser Configuration
-
-### Overview
-
-Changed default Playwright settings for better performance:
-- **Default browser:** Firefox (lower CPU usage)
-- **Default mode:** Headless (saves resources)
-
-### Modified Files
-
-#### `client.py`
-
-**Changes:**
-
-```python
-# BEFORE:
-DEFAULT_PLAYWRIGHT_HEADLESS = False
-
-# AFTER:
-DEFAULT_PLAYWRIGHT_HEADLESS = True
-DEFAULT_PLAYWRIGHT_BROWSER = "firefox"
-```
-
-**New function added:**
-```python
-def get_playwright_browser() -> str:
-    """
-    Get the browser to use for Playwright.
-    Options: chrome, firefox, webkit, msedge
-    Firefox is recommended for lower CPU usage.
-    """
-    return os.getenv("PLAYWRIGHT_BROWSER", DEFAULT_PLAYWRIGHT_BROWSER).lower()
-```
-
-**Playwright args updated:**
-```python
-playwright_args = [
-    "@playwright/mcp@latest",
-    "--viewport-size", "1280x720",
-    "--browser", browser,  # NEW: configurable browser
-]
-```
-
----
-
-#### `.env.example`
-
-**Updated documentation:**
-```bash
-# PLAYWRIGHT_BROWSER: Which browser to use for testing
-# - firefox: Lower CPU usage, recommended (default)
-# - chrome: Google Chrome
-# - webkit: Safari engine
-# - msedge: Microsoft Edge
-# PLAYWRIGHT_BROWSER=firefox
-
-# PLAYWRIGHT_HEADLESS: Run browser without visible window
-# - true: Browser runs in background, saves CPU (default)
-# - false: Browser opens a visible window (useful for debugging)
-# PLAYWRIGHT_HEADLESS=true
-```

-Let's call it Simple Todo. This is a really simple web app that I can use to track my to-do items using a Kanban
-board. I should be able to add to-dos and then drag and drop them through the Kanban board. The different columns in
-the Kanban board are:
-
-- To Do
-- In Progress
-- Done
-
-The app should use a neobrutalism design.
-
-There is no need for user authentication either. All the to-dos will be stored in local storage, so each user has
-access to all of their to-dos when they open their browser. So do not worry about implementing a backend with user
-authentication or a database. Simply store everything in local storage. As for the design, please try to avoid AI
-slop, so use your front-end design skills to design something beautiful and practical. As for the content of the
-to-dos, we should store:
-
-- The name or the title at the very least
-- Optionally, we can also set tags, due dates, and priorities which should be represented as beautiful little badges
-  on the to-do card Users should have the ability to easily clear out all the completed To-Dos. They should also be
-  able to filter and search for To-Dos as well.
-
-You choose the rest. Keep it simple. Should be 25 features.

-2. **Name**: A concise, descriptive name
-3. **Description**: What the feature should do
-4. **Steps**: How to verify/implement the feature (as a list)
+When a user asks to add a feature, use the `feature_create` or `feature_create_bulk` MCP tools directly:
+
+For a **single feature**, call `feature_create` with:
+- category: A grouping like "Authentication", "API", "UI", "Database"
+- name: A concise, descriptive name
+- description: What the feature should do
+- steps: List of verification/implementation steps
+
+For **multiple features**, call `feature_create_bulk` with an array of feature objects.
 
 You can ask clarifying questions if the user's request is vague, or make reasonable assumptions for simple requests.
 
 **Example interaction:**
 User: "Add a feature for S3 sync"
-You: I'll create that feature. Let me add it to the backlog...
+You: I'll create that feature now.
 [calls feature_create with appropriate parameters]
