Improve capture performance: shorter RX lock, PMKID-first save, channel sweep

- Reduce time spent in capture spinlock by snapshotting slot BSSIDs and
  only locking for shared-state updates
- Add PMKID KDE detection to save on EAPOL M1 when present
- Sweep channels with remaining WPA targets instead of camping one channel

Implement 4-phase capture architecture: observe, target, capture

- Phase 2 (Observation): passive client mapping from data frame headers,
  ClientInfo array per slot (up to 8 clients), 5s observation window
- Phase 3 (Targeting): unicast deauth burst to each discovered client
  instead of broadcast, reason code 7, 5 frames per client
- Phase 4 (Capture): timeout + retry loop cycles back to observation
  to refresh stale client list (2 cycles within 30s channel timeout)
- Fix EAPOL detection: compute LLC/SNAP offset from QoS vs non-QoS
  header length, verify AA-AA-03 SNAP prefix, skip protected frames
- Concurrency: portMUX spinlock for callback/main-loop shared state,
  no dynamic alloc in callback, pre-allocated 4KB PCAP buffer per slot
- Phase-aware LCD status display (mapping → capturing → EAPOL count)
