Lantern [Anti-Xray]

### Bug Fixes - Fixed detection confidence calculation — now uses weighted combination of max and average predictions for more accurate results - Fixed ore position tracking order — oldest entries are now properly removed first instead of random ones - Fixed straight-dig detection — counter now correctly checks actual mining direction instead of incrementing unconditionally - Fixed rare crash/race condition when clearing mining data during async model prediction - Fixed potential thread-safety issue with Discord webhook accessing player data from async thread ### Improvements - Webhook JSON is now built safely using Gson instead of raw string formatting - Removed unused legacy command handler (155 lines of dead code) - Internal performance and code quality improvements
