feat(agents): implement Code Commander module (Phases 1-5)

- Phase 1: Infrastructure (state, prompts, registry) - Phase 2: Execution engine (AI adapters, security classifier, executors) - Phase 3: Agent integration (graph nodes, routing) - Phase 4: Streaming interaction (PTY terminal, WebSocket) - Phase 5: Frontend integration (Vue components)
