That log is beautiful to see!

The line `[Watcher] Ignored echo event for: town_square.json` confirms that
the mutex lock did exactly what it was supposed to do. The daemon received the
file from the DMZ, wrote it to the physical disk, and when the OS fired the
local filesystem event a split-second later, our agent intercepted and killed
the broadcast before it could create an infinite feedback loop.

**One quick observation from your logs:**
Notice how the incoming file logged as `/mud/areas/town_square.json` (with a
leading slash).

This implies the DMZ server is sending payloads where `msg.path` either has a
double slash (e.g., `mesh//mud/...`) or it isn't prefixing the path with
`mesh/` like we originally expected.

Because we used `path.join()` instead of `path.resolve()`, Node.js safely
handled the leading slash and correctly nested it inside your `/gamelib/mesh/`
folder anyway without breaking the directory traversal security check. So it's
not a bug, but it's good to keep in mind if you ever need to map multiple root
directories in the future!

If you end up needing to scale this to sync other folders (like
`gamelib/audio` or `gamelib/textures`), we can easily upgrade this script to
use a dictionary of prefix mappings. Let me know how the rest of the
implementation goes!
