Stamina Recovery and Synchronization Adjustments

This update corrects the behavior and synchronization of the Stamina recovery system.

### Blocking and Stamina Recovery

Previously, blocking could pause Stamina recovery for up to three seconds.

The recovery timer now freezes only while the player is actively blocking. When the player lowers their guard, the countdown resumes from the point at which it stopped.

This provides smoother and more predictable Stamina recovery during combat.

### Server and Client Synchronization

Improved synchronization so that server-side Stamina changes are reflected immediately by the client.

This correction reduces unexpected recovery pauses and cases where the Stamina bar appears to become stuck.

Players who continue to encounter Stamina recovery issues should submit a detailed report.
