Server Authority combat hits feel delayed

Issue
Weapons are secure on the server but feel sluggish when the player attacks.

Cause
The client waits for a full round trip before showing any response.

Fix
Predict local animation, recoil, sound, and provisional effects immediately while the server validates the authoritative hit. Reconcile rejected results without granting damage, currency, or inventory locally. Keep timestamp and input validation within reasonable latency bounds.

Verify
Test at several latency levels and confirm feedback is immediate while damage remains server-controlled.
