What
MCP connection and cache maps, child-process tracking with its exit-time SIGTERM sweep, the transcript-recording hook, several path and homedir lookup caches, the plans-directory lookup and a text-width cache all moved from module-level globals into class instances reached through accessors, with ad-hoc reset() methods dropped in favour of releasing the holder.
