Merge main into feat/cursor-cli-integration

Carefully merged latest changes from main branch into the Cursor CLI integration
branch. This merge brings in important improvements and fixes while preserving
all Cursor-related functionality.

Key changes from main:
- Sandbox mode security improvements and cloud storage compatibility
- Version-based settings migrations (v2 schema)
- Port configuration centralization
- System paths utilities for CLI detection
- Enhanced error handling in HttpApiClient
- Windows MCP process cleanup fixes
- New validation and build commands
- GitHub issue templates and release process improvements

Resolved conflicts in:
- apps/server/src/routes/context/routes/describe-image.ts
  (Combined Cursor provider routing with secure-fs imports)
- apps/server/src/services/auto-mode-service.ts
  (Merged failure tracking with raw output logging)
- apps/server/tests/unit/services/terminal-service.test.ts
  (Updated to async tests with systemPathExists mocking)
- libs/platform/src/index.ts
  (Combined WSL utilities with system-paths exports)
- libs/types/src/settings.ts
  (Merged DEFAULT_PHASE_MODELS with SETTINGS_VERSION constants)

All Cursor CLI integration features remain intact including:
- CursorProvider and CliProvider base class
- Phase-based model configuration
- Provider registry and factory patterns
- WSL support for Windows
- Model override UI components
- Cursor-specific settings and configurations
