Greptile Summary

Optimized chat command prefix lookup in OnChat by replacing linear iteration through _localizedCommands with direct dictionary lookup via GetCommandPrefixByName, and caching the result to avoid duplicate method calls.

• Replaced O(n) iteration with O(1) dictionary lookup using pre-populated VanillaCommandsPrefixs dictionary
• Cached commandPrefix result to eliminate redundant GetCommandPrefixByName calls
• Added null/empty check for args.CommandId._name before lookup
• Behavior remains identical while significantly improving performance for every chat message using command IDs

Confidence Score: 5/5

• This PR is safe to merge with no risk
• Clean performance optimization that replaces inefficient iteration with dictionary lookup, caches results to avoid duplicate calls, and maintains identical behavior with proper null checks
• No files require special attention
