feat: centralize CLI tool path management (#341)

* feat: centralize CLI tool path management Created centralized CLI tool manager with multi-level detection priority (user config → venv → Homebrew → system PATH). Key changes: - New cli-tool-manager.ts with platform-aware detection (macOS Apple Silicon/Intel, Windows, Linux) - Migrated 75 hardcoded CLI tool usages across 12 files (Python, Git, GitHub CLI) - Added Settings UI for user configuration with auto-detection display showing detected path, version, and source - Implemented version validation (Python 3.10+ required) - Session-based caching without TTL expiration - Full i18n support (EN/FR) for new Settings UI elements This eliminates hardcoded tool paths and provides consistent, configurable CLI tool management across the application. * fix(lint): resolve linting issues in CLI tool manager - Remove unused getAugmentedEnv import - Replace console.log with console.warn for logging - Fix template string syntax error in release-service.ts (backtick vs quote) Reduces lint errors from 185 to 179 (0 errors, 179 warnings) * fix(security): address CodeRabbit review feedback - Fix command injection vulnerability in validateGitHubCLI using execFileSync - Remove redundant execSync calls in release-service.ts - Fix Electron context separation by moving ToolDetectionResult to shared types - Add loading state to Settings UI to prevent flashing 'Not detected' - Improve error handling with safe string conversion Addresses security and code quality issues identified by automated review. * fix(security): fix all command injection vulnerabilities in CLI tool usage Replace all execSync calls using getToolPath() with execFileSync to prevent command injection attacks. This fixes CodeQL security warnings about unsanitized environment variables in command execution. Changes: - settings-handlers.ts: 1 fix (git init) - release-service.ts: 20 fixes (git/gh commands in release flow) - worktree-handlers.ts: 22 fixes (git worktree operations) - project-handlers.ts: 3 fixes (git branch operations) - github/utils.ts: 1 fix (gh auth token) - github/oauth-handlers.ts: 11 fixes (gh API and git remote operations) - github/release-handlers.ts: 3 fixes (gh auth, git describe, git log) - changelog/git-integration.ts: 6 fixes (git branch and tag operations) Total: 67 command injection vulnerabilities fixed Security Impact: - Prevents malicious users from injecting arbitrary commands via CLI tool paths - Uses execFileSync which executes binaries directly without shell interpolation - Passes arguments as array instead of concatenated string - Eliminates shell redirection patterns (2>/dev/null) with try-catch blocks * fix(security): fix remaining command injection vulnerabilities and remove unused imports Fix all remaining CodeQL security warnings: CLI tool validation (cli-tool-manager.ts): - validateGit: Replace execSync with execFileSync for git --version Project initialization (project-initializer.ts): - Replace all 7 execSync calls with execFileSync - git rev-parse, git init, git status, git add, git commit Release service (release-service.ts): - checkTagExists: Fix git tag -l and git ls-remote - getGitHubReleaseUrl: Fix gh release view - Fix worktree merge detection (2 more git commands) - Remove unused execSync import Code cleanup: - Remove unused execSync imports from: - github/utils.ts - project-handlers.ts - settings-handlers.ts - release-service.ts Total: 12 additional command injection fixes + 4 unused imports removed This completes the security audit with 0 remaining vulnerabilities. * refactor(code-quality): remove useless variable assignments Fix CodeQL warnings about unused initial variable values: - mainBranch: Declare without initial value, assign in try-catch - unmergedCommits: Declare without initial value, assign in try-catch The initial values were never used since they were always overwritten either in the try block (success) or catch block (error fallback). * test(security): update oauth-handlers tests to use execFileSync mocks Update test mocks in oauth-handlers.spec.ts to match the security fix that changed from execSync to execFileSync. All 525 tests now passing. Changes: - gh CLI Check Handler tests: Use mockExecFileSync with array args - gh Auth Check Handler tests: Use mockExecFileSync with array args - Fixed argument pattern: cmd + args array instead of single command string Related to command injection prevention in oauth-handlers.ts
