feat: migrate scripts to Bun runtime

- Updated shebangs in user-message-hook.js, worker-cli.js, and worker-service.cjs to use Bun instead of Node.
- Modified build-hooks.js to generate Bun-compatible shebangs in built scripts.
- Enhanced sync-marketplace.cjs to trigger a worker restart after syncing files via an HTTP request.
- Improved worker-cli.ts to exit with appropriate status codes after executing commands.
- Added build-worker-binary.js to create a Windows executable for the worker service using Bun's compile feature.
