test: add unit tests for exec-utils, feature verification, project analysis, and task execution

- Introduced comprehensive unit tests for exec-utils, covering execAsync, extendedPath, execEnv, and isENOENT functions.
- Added tests for FeatureVerificationService to validate feature verification and commit processes.
- Implemented tests for ProjectAnalyzer to ensure project analysis functionality.
- Created tests for TaskExecutor to validate task execution and event emissions.

These additions enhance test coverage and ensure the reliability of core functionalities.

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Automaker is an autonomous AI development studio - a Kanban-based application where users describe features and AI agents (powered by Claude Agent SDK) automatically implement them. It runs as an Electron desktop app or in web browser mode.
+
+## Commands
+
+```bash
+# Install dependencies
+npm install
+
+# Build shared packages (REQUIRED before running)
+npm run build:packages
+
+# Development
+npm run dev               # Interactive mode selector
+npm run dev:electron      # Electron desktop app
+npm run dev:web           # Web browser mode (localhost:3007)
+npm run dev:server        # Backend server only
+
+# Testing
+npm run test              # UI E2E tests (Playwright)
+npm run test:headed       # UI tests with visible browser
+npm run test:server       # Server unit tests (Vitest)
+npm run test:packages     # Shared package tests
+
+# Linting & Formatting
+npm run lint              # ESLint
+npm run format            # Prettier
+npm run format:check      # Check formatting
+
+# Building
+npm run build             # Build Next.js app
+npm run build:electron    # Build Electron distribution
+```
+
+## Architecture
+
+### Monorepo Structure (npm workspaces)
+
+```

+├── ui/          # Electron + Vite + React frontend (@automaker/ui)
+└── server/      # Express + WebSocket backend (@automaker/server)

+└── dependency-resolver/ # Dependency management
+```
+
+### Key Patterns
+
+**State Management (UI)**: Zustand stores in `apps/ui/src/store/`
+
+- `app-store.ts` - Main application state (features, settings, themes)
+- `setup-store.ts` - Project setup wizard state
+
+**Routing (UI)**: TanStack Router with file-based routes in `apps/ui/src/routes/`
+
+**Backend Services**: Express + WebSocket in `apps/server/src/`
+
+- Services in `/services/` handle business logic
+- Routes in `/routes/` define API endpoints
+- Providers in `/providers/` abstract AI model integrations
+
+**Provider Architecture**: Model-based routing via `ProviderFactory`
+
+- `ClaudeProvider` wraps @anthropic-ai/claude-agent-sdk
+- Designed for easy addition of other providers
+
+**Feature Storage**: Features stored in `.automaker/features/{id}/feature.json`
+
+**Communication**:
+
+- Electron: IPC via preload script (`apps/ui/src/preload.ts`)
+- Web: HTTP API client (`apps/ui/src/lib/http-api-client.ts`)
+
+### Important Files
+
+- `apps/ui/src/main.ts` - Electron main process
+- `apps/server/src/index.ts` - Server entry point
+- `apps/ui/src/lib/electron.ts` - IPC type definitions
+- `apps/server/src/services/agent-service.ts` - AI agent session management
+- `apps/server/src/providers/provider-factory.ts` - Model routing
+
+## Development Notes
+
+- Always run `npm run build:packages` after modifying any `libs/*` package
+- Server runs on port 3008 by default
+- UI runs on port 3007 in web mode
+- Authentication: Set `ANTHROPIC_API_KEY` env var or configure via Settings

-export const ISSUE_VALIDATION_SYSTEM_PROMPT = `You are an expert code analyst validating GitHub issues against a codebase.
-
-Your task is to analyze a GitHub issue and determine if it's valid by scanning the codebase.
-
-## Validation Process
-
-1. **Read the issue carefully** - Understand what is being reported or requested
-2. **Search the codebase** - Use Glob to find relevant files by pattern, Grep to search for keywords
-3. **Examine the code** - Use Read to look at the actual implementation in relevant files
-4. **Form your verdict** - Based on your analysis, determine if the issue is valid
-
-## Verdicts
-
-- **valid**: The issue describes a real problem that exists in the codebase, or a clear feature request that can be implemented. The referenced files/components exist and the issue is actionable.
-
-- **invalid**: The issue describes behavior that doesn't exist, references non-existent files or components, is based on a misunderstanding of the code, or the described "bug" is actually expected behavior.
-
-- **needs_clarification**: The issue lacks sufficient detail to verify. Specify what additional information is needed in the missingInfo field.
-
-## For Bug Reports, Check:
-- Do the referenced files/components exist?
-- Does the code match what the issue describes?
-- Is the described behavior actually a bug or expected?
-- Can you locate the code that would cause the reported issue?
-
-## For Feature Requests, Check:
-- Does the feature already exist?
-- Is the implementation location clear?
-- Is the request technically feasible given the codebase structure?
-
-## Response Guidelines
-
-- **Always include relatedFiles** when you find relevant code
-- **Set bugConfirmed to true** only if you can definitively confirm a bug exists in the code
-- **Provide a suggestedFix** when you have a clear idea of how to address the issue
-- **Use missingInfo** when the verdict is needs_clarification to list what's needed
-- **Set estimatedComplexity** to help prioritize:
-  - trivial: Simple text changes, one-line fixes
-  - simple: Small changes to one file
-  - moderate: Changes to multiple files or moderate logic changes
-  - complex: Significant refactoring or new feature implementation
-  - very_complex: Major architectural changes or cross-cutting concerns
-
-Be thorough in your analysis but focus on files that are directly relevant to the issue.`;
