Track devices across MAC rotations using BLE Handoff sequence numbers and DHCP Option 55 fingerprinting. Auto-enroll personal devices when seen on 2+ independent signal types. Handle iOS MAC rotation silently. Confidence-based departure only fires for enrolled devices. Changes: - New device_store dict for stable device identity tracking (keyed by handoff seq anchor or DHCP fingerprint hash) - _dhcp_fingerprint_hash() computes stable DHCP Option 55 fingerprint - _create_identity_record() initializes device records - _on_device_enrolled() triggers silent enrollment when signal_count >= 2 - _correlate_or_create_identity() finds or creates identities via BLE seq or DHCP fingerprint, handles MAC rotation detection - _ingest_signal() ingests signals from multiple sources (BLE, DHCP, ARP, mDNS) and triggers enrollment when criteria met - ble_sniffer() thread for Apple Continuity Protocol parsing (HCI socket + hcidump fallback); graceful failure on missing hardware - Modified parse_frame() to extract DHCP Option 55 and ingest signals for ARP, mDNS, DHCP packets - Updated main() to start BLE sniffer thread and log device_store stats
