• Implements a memoization decorator with TTL for State.get() to reduce database queries.
• Adds in-memory cache with locking for state objects.
• Improves path matching logic in potential_frame_match and RepoClient.get_valid_file_paths with confidence scores to handle partial matches more effectively.
• Increases lru_cache size for get_valid_file_paths from 8 to 32.
• Adds logging for debugging path matching issues.
• Handles exceptions when getting valid file paths and returns an empty set instead of failing.
• Clears state cache before updating a state to ensure data consistency.
