🛡️ Sentinel: [security improvement]

[NoWon1]

🚨 Severity: MEDIUM
💡 Vulnerability: Bare except blocks catch BaseException, potentially swallowing critical system signals (like KeyboardInterrupt or SystemExit) leading to localized DoS.
🎯 Impact: Could prevent graceful shutdown and mask critical system errors.
🔧 Fix: Replaced all bare except: blocks with except Exception: to only catch standard exceptions.
✅ Verification: Review the code changes and verify with bandit and pytest.
