Subject: [PATCH] Refactor non-global plugin retrieval for performance
 optimization

Refactored plugin lookup in ValidPluginsForQuery to use a new
TryGetNonGlobalPlugins method, which safely copies plugin lists
using a lock. This improves thread safety and performance
when accessing non-global plugins.
