Switch from polling /v1/receive every 2s to a persistent WebSocket
connection at ws://.../v1/receive/<number>. Messages now arrive
instantly via the signal-cli-rest-api WebSocket endpoint.
- Add `listen()` generator to SignalClient using websockets library
- Extract `_parse_envelope()` as standalone function
- Replace `run_loop` polling with WebSocket listener + reconnect logic
- Remove `poll_interval` from BotConfig and CLI args
- Add websockets to Nix overlay and pyproject.toml dependencies

Python service for jeeves that communicates over Signal via signal-cli-rest-api.
Implements device verification via safety numbers (unverified devices cannot
run commands until verified over SSH), and a van inventory command that uses
an LLM on BOB (ollama) to parse receipt photos or text lists into structured
inventory data. The LLM backend is configurable to swap models easily.
