Subject: [PATCH 1/2] Add mise.toml and biome tooling to frontend

Sets up mise tooling with:
- Node 22
- install: make install (installs both frontend and backend)
- lint: biome check in frontend (added biome + scripts)
- format: biome format --write in frontend (added biome + scripts)
- test: placeholder in frontend

Added to frontend/:
- biome.json config
- @biomejs/biome dev dependency
- Updated scripts to use biome instead of eslint
