Phase 1: single agent + basic UIHEADmain

- Bun monorepo with @dispatch/core, @dispatch/api, @dispatch/frontend
- Agent runtime with Vercel AI SDK, streaming via WebSocket
- Tools: read_file, write_file, list_files (scoped to working directory)
- Hono API server with POST /chat, GET /status, GET /health, WS /ws
- Svelte 5 + DaisyUI frontend with chat UI, theme switcher, copy button
- OpenCode Go (Zen) as LLM provider, deepseek-v4-flash-free model
- Docker setup (dev + prod) with bin/ scripts and gopass secrets
- Biome v2 linting/formatting, Vitest tests (44 passing)
- Debug info attached to error messages for diagnostics
