Clean up test diagnostic files

A debug-print attempt from earlier inadvertently appended a second
_rollback_tick function (with spaces instead of tabs) at the end of
weapon_manager.gd:419, causing the entire script to fail compilation.
This meant the WeaponManager node had NO script attached:
- 'has_method("set_default_loadout")' returned false
- Client-side loadout init never ran
- All weapon operations silently did nothing

This is the real root cause of why weapons never worked on the client.
