🧹 Refactor error handling in debug_log to log OSErrors instead of silently passing

[google-labs-jules]

🎯 What: Modified hooks/security_guard.py and hooks/secret_scanner.py's debug_log functions. Replaced except Exception: pass with except OSError as e: and added a print statement.
💡 Why: Silently catching Exception hides unrelated errors (NameError, TypeError) and masking IOError failures makes logging issues difficult to debug.
✅ Verification: Ran pytest tests directly and manually checked that python -m py_compile works, plus completed code review ensuring sys.stderr was safe. Made sure __pycache__ artifacts are removed.
✨ Result: Improved maintainability, debuggability, and consistency across codebase hook scripts.

Closing in favor of #17, which consolidates all 16 open hook PRs into one coherent change (they overlapped and conflicted with each other, so they could not be merged independently). Closing without merging: narrowing debug_log from except Exception to OSError plus printing to stderr makes a best-effort logger less crash-safe and noisier inside a hook. #17 keeps the logger crash-safe; the genuine fix was for state saves (see #4), which #17 includes.

Understood. Acknowledging that this work is now obsolete as it has been superseded by #17, and stopping work on this task.
