Fix hot-dev reload to detect new .go file creation

The file watcher was only triggering on .go file modifications but missing new file creation. This happened because inotifywait sometimes reports the directory path first when a file is created.

Changes:
- Include event type in inotifywait output format
- Trigger rebuild on CREATE/DELETE/MOVED events in addition to .go modifications
- Add exclusions for temp files (.swp, .tmp, ~)

Now creating new .go files will trigger an auto-rebuild.
