Notes and limitations

"Check for Leftover Mock Endpoints" greps the workspace for the literal localhost:<port> / 127.0.0.1:<port> strings of ports used by mock servers started this session — it does not persist across VS Code restarts and won't catch endpoints referenced through an environment variable or config indirection. Auto-detection of which third-party SDKs are in play (so MockAgent could suggest fixtures automatically) is not implemented; it's an unimplemented v2 stretch goal.
