WorldProtect

[Regions / Limits]
- Region limits reworked: different region sizes and claim counts are now fully configurable (set any values you want in the config).

[Commands / GUI]
- Added /rg menu (GUI region menu):
  - Players can open/manage only their own regions.
  - Admins can open/manage any region via /rg menu <regionId> (requires permission).
- /rg wand can now be enabled/disabled per world via config.
- Improved /rg reload behavior (more reliable reload with better validation).
- Added a new permission for the legacy command /rg setpriority.

[Config / Data]
- Configuration improvements + multiple config fixes (better defaults, safer parsing/handling).
- Added automatic backup saves for region data.

[Performance]
- Optimized the in-game map (M) region updates: no more heavy lag — only the affected area is refreshed instead of rewriting the whole map.
- Implemented async saving to prevent server lag during saves.

[Protection / Fixes]
- Fixed PvP flag logic: PvP deny now works correctly (including DoT effects like fire/poison) and cannot be bypassed.
- Fixed liquids: water/lava placed outside can no longer flow into protected regions (stops at claim borders).
- Added protection against explosions (ExplodeInteraction) to prevent bypassing build protection.

[New Flags]
- light-access
- door-access
- item-pickup (ground/contact pickup)
- item-grab (manual pickup via F)
