- fyPromotePrevSession now reads session.json, writes to prev_session.json,
then deletes the original — SPIFFS.rename() silently fails on ESP32
- prior session KML export: added style defs, raven metadata, error handling,
moved file validation before response stream init
- reduced auto-save interval 60s → 15s, added 5s quick-save on first detection
Complete rewrite of standalone Flock-You firmware:
- Remove WiFi promiscuous mode, all detection is now BLE-only
- Add web dashboard served on AP "flockyou" at 192.168.4.1
- GPS wardriving via phone browser Geolocation API
- SPIFFS session persistence with auto-save every 60s
- Prior session tab (PREV) survives reboots
- KML export for Google Earth (current + prior session)
- JSON/CSV export with GPS coordinates
- Serial JSON output for Flask live ingestion
- Crow call boot sounds with detection/heartbeat alerts
- 200 unique device storage with FreeRTOS mutex
- Flask app: add KML import endpoint, GPS data handling
- Update platformio.ini with AsyncWebServer, ArduinoJson 7, SPIFFS partition
- Rewrite README to reflect current functionality
