Learning: Using re.search with string patterns in tight loops (like those in ExecutionSafetyManager) introduces unnecessary overhead. Bypassing the cache by executing pre-compiled re.Pattern objects (p.search(text)) is measurably faster.
Action: Always pre-compile regular expressions as class-level attributes using generator expressions converted to tuples (e.g., tuple(re.compile(p) for p in _PATTERNS)) when optimizing repeated regex matching with any() inside class methods.
