Phase 7: Windows client export, preset fix, code fixes

- Fix: export_presets.cfg — platform='Windows Desktop' (not 'Windows'), Windows as [preset.0]
- Fix: plugin_manager.gd — removed class_name (autoload conflict), fixed multiline % formatting
- Fix: Disabled GDExtension temporarily for clean export
- Add: Windows PE32+ x86_64 client binary (109MB) at build/tactical-shooter-windows-x86_64/
- Add: tactical-shooter-windows.zip (portable zip package)
- Build: Linux server binary (78MB) rebuilt

+## WeaponManager — hitscan weapon system for tactical FPS.

+## Manages a single hitscan weapon: fire rate limiting, ammo, reload.
+## Communicates with SimulationServer for server-authoritative hit detection.

+## Architecture:
+##   - Client-side: fire rate limiting, muzzle VFX, hit marker feedback
+##   - Server-side (via SimulationServer): hit detection, damage, lag compensation
+##   - Both sides: ammo tracking (server-authoritative, client-predicted)
+##
+## Usage (attach as child of FPSCharacterController):
