* feat(mcp): add stdio host for local clients
* feat(mcp): add Streamable HTTP host and image
Long-lived HTTP entry for Docker and other process hosts, reusing
createServer(). Dedicated mcp/Dockerfile; compose service beside api.
* fix(mcp): stdio launcher cwd/silent and HTTP session bounds
Pin bun --cwd so bunfig loads. Silence bun run. Require Bearer on HTTP.
Idle-expire and cap in-memory MCP sessions.
* fix(mcp): re-check bearer on established HTTP sessions
Session lookup returned early without Authorization, so a missing or
wrong token still 200'd after initialize. Bind each session to the
init key and 401 on mismatch.
* fix: nit cleaning claude command
