Overview

Pre-populates the introspection cache during Rails boot.

Calling .warm triggers a full introspection pass so that the first MCP tool call returns instantly from cache rather than blocking on a cold introspection. Errors are logged and swallowed — warming is best-effort and must never prevent the app from starting.
