Performance Fix & LuckPerms H2 Migration

This release includes a critical performance fix and completes LuckPerms H2 database migration support.

Performance Fix

Cache Bypass Fix in Permission Checks

Fixed a critical performance issue where HyperPermsPermissionSet.contains() was bypassing the Caffeine permission cache, triggering a full permission resolution on every call. This was consuming 6.5% CPU in profiling.

Technical Details:

• Added checkPermission() method to HyperPerms that returns TriState and properly uses the cache
• Refactored HyperPermsPermissionSet.contains() to use the cached lookup instead of calling resolver directly
• Removed redundant getOrLoadUser() private method

Performance Impact:

• Before: Every contains() call triggered full resolve() - O(n groups * m nodes)
• After: Cache hit = O(1) lookup; cache miss = resolve + cache store
• Expected 90%+ reduction in CPU time for permission checks

LuckPerms H2 Migration Support

Command Syntax Update

Due to Hytale command framework limitations, migration options now use dash-separated syntax:

/hp migrate luckperms-confirm-verbose

H2 Database Reader Enhancements

• Dynamically loads H2 driver from LuckPerms libs/ folder for version compatibility
• Handles locked databases by creating temporary copies
• Fixed connection URL to use absolute paths (required by H2 2.1.x+)
• Set thread context classloader for proper class isolation
• H2 is now compileOnly to avoid version conflicts with bundled driver

Storage Detection Improvements

• Fixed path resolution to correctly find LuckPerms in /mods/ folder
• Case-insensitive folder name detection (finds LuckPerms_LuckPerms, etc.)
• Flexible pattern matching for database files
• Support for various LuckPerms folder naming conventions

Windows Support

• Added clear error message for Windows file locking issues
• Users are directed to stop LuckPerms before migrating when database is locked
