Extends the gateway wire protocol with GatewayAttachment type and
attachment event. agent.send handler now accepts optional attachments
parameter and converts them for the agent pipeline. Includes 5 new
tests for protocol and handler layers.
Phase 2 of the Flynn roadmap. Adds a WebSocket gateway server that
starts alongside the Telegram bot, providing real-time API access to
the agent, sessions, and tools.
Protocol: JSON-RPC-like (request/response/event) over WebSocket.
8 methods: agent.send, agent.cancel, sessions.list, sessions.history,
sessions.create, tools.list, tools.invoke, system.health.
Auth: Bearer token + Tailscale identity header support.
Session bridge: per-connection agent instances with shared model router.
New files: src/gateway/ (protocol, router, server, auth, session-bridge,
handlers for agent/sessions/tools/system).
57 new tests (181 total), typecheck clean.
