Adds DPSMate_CLEUAdapter.lua -- replaces DPSMate's string-parsing
CHAT_MSG_* system with structured COMBAT_LOG_EVENT data from our DLL.
Adapter maps CLEU subevents directly to DPSMate.DB API calls:
DamageDone, DamageTaken, EnemyDamage, Healing, HealingTaken,
DeathHistory, Kick, Dispels, BuildBuffs, CCBreaker, etc.
Eliminates all strfind pattern matching from the combat log path.
Toggle: /dpscleu (on/off/status)
Benchmark: /dpsbench -- always-on per-combat A/B profiling.
Resets at combat start, reports at combat end, flips mode for next
combat. Reports events, total ms, us/event, GC delta, and percentage
comparison between CLEU and original modes.
Starts in CLEU mode by default.
