x64 Server Testing and Client Performance Improvements

Testing of the RaiderZ Global x64 server build has begun, with the new architecture showing promising early results.

Issues that were previously difficult to diagnose are already showing improvement. This includes combat-related NPC positioning problems affecting encounters such as KTX.

### Client Performance Testing

A client-side optimization is also being tested with the current North American client binary.

The change targets a long-standing issue that caused frame rates to gradually decrease:

- After remaining online for an extended period

- During or after combat-intensive situations

Previously, players had to reconnect their characters to restore normal performance.

During early testing, frame rates remained stable across longer play sessions and combat-heavy scenarios.

These improvements were still under active testing and required additional stability verification before being considered complete.
