* fix(mcp): canonicalize the daemon rendezvous root on Windows
A project spelled d:\work\codegraph or D:\work\codegraph is one directory, but the daemon socket/pipe name and the registry record name hashed a raw path.resolve, which preserves whichever casing the caller passed. A proxy that computed the other casing probed a socket nobody bound, spawned a redundant daemon, and that daemon exited on the lock the running one held, so the session silently served the graph in-process: no shared watcher, no auto-sync, one extra copy of the index per open window.
Both names now come from one shared canonicalProjectRoot (native realpath, lowercased on win32), so every spelling meets the same daemon and codegraph list / stop --all see one record per project.

* fix(mcp): share one in-process project however its root is cased (#2278)
The engine's project lifecycle and `codegraph stop`'s registry fallback keyed
a project by its realpath, which keeps the caller's casing, so two spellings
of one root opened two graphs and two watchers in one process. Both now use
the same identity key as the daemon socket.
