Cobblemon: Extended Battle UI

Bug Fixes

• Stat Tracking - Fixed stat changes not being tracked correctly in many scenarios. Refactored the entire stat tracking system to properly parse battle messages. Now correctly handles all stat manipulation moves (Haze, Topsy-Turvy, Heart Swap, Power Swap, Guard Swap, Speed Swap, Psych Up, Belly Drum, Anger Point).
• Mirror Match Handling - Fixed bug where having the same Pokémon species on both sides would cause stat changes to be applied to the wrong Pokémon.
• Spectator Exit - Fixed battle state not clearing when exiting a battle as a spectator.

Improvements

• Dynamic UI Labels - Section headers now display actual player names instead of static "ALLY" / "ENEMY" labels.

Internal

• Added move tracking cleanup to prevent stale data across battles
