The bare `except:` clause catches SystemExit which is raised by
sys.exit(0), causing the script to fall through to sys.exit(1).
Changed to `except Exception:` which doesn't catch SystemExit,
allowing proper exit code propagation.
Also:
- Simplified Python extraction script
- Use double quotes for string literals (shell compatibility)
- Write Python script to temp file instead of heredoc (RPCD stdin conflict)
