🐛 Bug Fixes

**Windows Installation**
- Fixed Bun PATH detection on Windows after fresh install
- Added fallback to check common install paths before PATH reload
- Improved smart-install.js to use full Bun path when not in PATH
- Added proper path quoting for Windows usernames with spaces

**Worker Startup**
- Fixed worker connection failures in Stop hook
- Added health check retry loop (5 attempts, 500ms intervals)
- Worker now waits up to 2.5s for responsiveness before returning
- Improved error detection for Bun's ConnectionRefused error format
