chore: update build process and add Docker support

- Modified build script in package.json to include minification.
- Removed unused dev server dependency from vite.config.ts.
- Added .dockerignore to exclude unnecessary files from Docker context.
- Created Dockerfile for multi-stage build with Bun for production deployment.
