New docs/MCP-INTEGRATION.md: how the two Hermes instances connect via MCP
using colibri-mcp as the hub-and-spoke front-end to the shared board, rather
than a direct mesh. Grounded in actual code:
- Hermes is both MCP server (hermes mcp serve) and client (mcp_servers config)
- colibri-mcp tool surface + env vars (COLIBRI_MCP_SOCKET/WRITE), socket transport
- ties into the live board + poller/worker loop and the socat cross-host bridge
- LIVE/SETUP/PLANNED tags; security, rejected mesh alternative, external-MCP future
