Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-opencode)
- Rewrite release.yml: semantic-release for auto-versioning + Docker
image build and push to GitHub Container Registry (ghcr.io)
- Rewrite ci.yml: remove continue-on-error on lint
- Add .releaserc.json with changelog and git plugins
- Add semantic-release dependencies to package.json
- Fix Dockerfile: remove --frozen-lockfile from production install
- Update .dockerignore with comprehensive exclusions
- Update docker-compose.yml to pull from GHCR by default
- Remove obsolete pnpm packageManager field
- Remove obsolete kubernetes.yaml from .gitignore
- Add @biomejs/biome as dev dependency
- Remove deprecated tslint dependency
- Add biome.json with project-specific rules
- Update lint script to use Biome
- Apply Biome auto-fixes across codebase
- Add concurrently package for parallel process execution
- Split dev script into dev:backend and dev:frontend
- Use concurrently to run both with colored, labeled output
This enables single-command development with 'bun run dev' that starts
both the backend server (with hot reload) and frontend dev server.
