Refactor database integration to use bun:sqlite instead of better-sqlite3

- Updated import statements across multiple files to use bun:sqlite.
- Changed database query methods from `prepare` to `query` for consistency.
- Removed dependency on better-sqlite3 from package.json and adjusted package.json to specify bun as the engine.
- Modified hook installation process to eliminate unnecessary dependency installation.
- Updated migration scripts to align with bun:sqlite's API.
