fix: Complete fix for plan mode system across all providers

Closes #671 (Complete fix for the plan mode system inside automaker)
Related: #619, #627, #531, #660

## Issues Fixed

### 1. Non-Claude Provider Support
- Removed Claude model restriction from planning mode UI selectors
- Added `detectSpecFallback()` function to detect specs without `[SPEC_GENERATED]` marker
- All providers (OpenAI, Gemini, Cursor, etc.) can now use spec and full planning modes
- Fallback detection looks for structural elements: tasks block, acceptance criteria,
  problem statement, implementation plan, etc.

### 2. Crash/Restart Recovery
- Added `resetStuckFeatures()` to clean up transient states on auto-mode start
- Features stuck in `in_progress` are reset to `ready` or `backlog`
- Tasks stuck in `in_progress` are reset to `pending`
- Plan generation stuck in `generating` is reset to `pending`
- `loadPendingFeatures()` now includes recovery cases for interrupted executions
- Persisted task status in `planSpec.tasks` array allows resuming from last completed task

### 3. Spec Todo List UI Updates
- Added `ParsedTask` and `PlanSpec` types to `@automaker/types` for consistent typing
- New `auto_mode_task_status` event emitted when task status changes
- New `auto_mode_summary` event emitted when summary is extracted
- Query invalidation triggers on task status updates for real-time UI refresh
- Task markers (`[TASK_START]`, `[TASK_COMPLETE]`, `[PHASE_COMPLETE]`) are detected
  and persisted to planSpec.tasks for UI display

### 4. Summary Extraction
- Added `extractSummary()` function to parse summaries from multiple formats:
  - `<summary>` tags (explicit)
  - `## Summary` sections (markdown)
  - `**Goal**:` sections (lite mode)
  - `**Problem**:` sections (spec/full modes)
  - `**Solution**:` sections (fallback)
- Summary is saved to `feature.summary` field after execution
- Summary is extracted from plan content during spec generation

### 5. Worktree Mode Support (#619)
- Recovery logic properly handles branchName filtering
- Features in worktrees maintain correct association during recovery
