Robust Scan Recovery (#40)

Production-hardened Bluetooth scanning for single-adapter devices (e.g. Raspberry Pi 3B):

• InProgress detection — immediately stops scanning when BlueZ gets stuck, preventing D-Bus FD leaks from repeated retries
• Sysfs rfkill recovery — resets the Bluetooth adapter via /sys/class/rfkill (works even when file descriptors are nearly exhausted)
• Process exit after recovery — os._exit(0) gives a fresh process with clean FDs and new D-Bus connections
• Crash-loop prevention — if uptime < 3 min, sleeps 5 min instead of restarting again
• SQLite WAL mode — enables concurrent readers during writes, eliminating database is locked errors
