refactor(lua): replace single LState with LState pool architecture
Replace the single LState + coroutine model with an LState pool to eliminate concurrent map read/write issues in gopher-lua. Each request now gets a completely independent LState with its own Global table. Key changes: - Add LStatePool for managing pooled LState instances - Remove shared Engine.L and coroutine-based execution - Simplify coroutine.go: remove yield handling, use direct PCall - Remove ngxRegisterMu lock (no longer needed with isolated LStates) - Update config.go: add LStatePoolInitialSize/MaxSize settings - Update tests to work with the new architecture Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
