Moved main files to the "src" directory and updated paths accordingly. Adjusted build, start, and dev scripts to use Bun. Added "dist" directory to .gitignore to prevent it from being tracked.
Added TypeScript type definitions in `lib.d.ts` to improve developer experience and ensure type safety. Updated `package.json` to include the new "types" field and modified `.gitignore` to exclude additional unwanted files.
