💡 What: Upgraded the synchronized PATTERN_CACHE lookup to avoid synchronization bottlenecks.
🎯 Why: Instead of block-synchronizing the LRUCache, we use a ConcurrentHashMap for highly concurrent, lock-free pattern reads. To bound memory, we do not need the LRUCache eviction logic because the number of distinct path templates is statically limited by the user's workspace configuration, avoiding cache eviction overhead altogether.
📊 Impact: O(1) lock-free regex caching matching across multiple concurrent file matches.
🔬 Measurement: Reduced blocking threads inside resolveGroups.


PR created automatically by Jules for task 4680037672866663248 started by @RoiSoleil

Replaced synchronized LRUCache with a lock-free ConcurrentHashMap.
This prevents blocking across threads when multiple test paths evaluate
regular expressions concurrently. Given that workspace configurations
are static, cache evictions are unnecessary, rendering the LRU bound
superfluous.
