feat(lock): Optimize lock management performance in high-concurrency scenarios (#523)

Browse Source 
Increase the size of the notification pool to reduce the thundering herd effect under high concurrency
Implement an adaptive timeout mechanism that dynamically adjusts based on system load and priority
Add a lock protection mechanism to prevent premature cleanup of active locks
Add lock acquisition methods for high-priority and critical-priority locks
Improve the cleanup strategy to be more conservative under high load
Add detailed debug logs to assist in diagnosing lock issues
