feat(operator): Phase 1 — Claude-driven room bridge (join/read/say)
Invert the agent model: a headless OperatorBridge(Client) owns the websocket while a Claude Code session drives it via a unix control socket. Reuses Client SRP/Fernet and AgentBridge's reconnect/serve shape. Ships an hh-bridge CLI (up/read/say/roster/status/down) with a seq'd in-RAM inbox + asyncio.Condition long-poll (read --wait) for in-turn autonomy. ACL/sandbox-status frames are recorded for later phases. Sandbox drive, delegation and nesting are out of scope here. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
