Root cause: autoReconnect was false on init, so the
centralManagerDidUpdateState(.poweredOn) callback was a no-op.
User had to tap 'Scan' to set autoReconnect=true and start scanning.
Fixes:
- Set autoReconnect=true before creating CBCentralManager so the
.poweredOn callback immediately starts scanning on every app launch
- Scan timeout (15s): on expiry, call reconnectAfterDelay() instead
of staying idle — retries every 2s until TAG is found (handles
TAG still booting after firmware flash)
Behaviour after this change:
Launch → auto-scan within ~1s of Bluetooth ready
TAG not found after 15s → retry after 2s, repeat indefinitely
TAG disconnects → rescan after 2s
TAG reboots/reflashes → found within one 15s scan window
User taps Disconnect → autoReconnect=false, stops all retries
