9a56baef61 Rework BT poller and S300 decoding after client feedback
Client reported crashes, wrong/frozen data and that the app floods the
adapter MCU. See docs/FIX_2026-10-12.md for the full analysis.

- Poller: strictly one request outstanding; next request only after a valid
  128-byte reply or a 500 ms timeout, then a quiet period + buffer flush.
  Default 100 ms (10 Hz), minimum 80 ms. DTC clear/probe share the same lock.
- BtNotifier: filter the adapter's default (no-ECU-data) frame instead of
  holding last values; EcuDataStatus + status banner; auto-reconnect on link
  loss, stalls or long default-only runs (rate-limited). A reconnect still in
  flight when the user disconnects is discarded.
- S300 offsets corrected by column counting (trims, PA, ERR00-03, Eth, SW5,
  AF); INJ/AIN little-endian; fan = SW5 FANC only. Default-frame detection
  requires bytes 0-16 and 32-36.
- KPro RPM/MAP2/AIN little-endian (RPM still needs a bench check).
- Crash hardening: zone/Flutter/platform error handlers to an in-app log
  (copyable from Debug); permissions requested before listing devices.
- Remove temporary debug prints; graph redraws live; polling options
  100-300 ms, persisted.

e9b1c0f8fd Fuel pump flag, confirmed ECT/IAT/BAT offsets, persisted ECU type
Work that was previously only in the local working tree:
- Rename fuelCut -> fuelPump (SW2 bit2, active-low, live-confirmed)
- ECT/IAT/BAT moved to live-confirmed offsets 33/34/36
- S300 template-frame detection with hold-last-good logic
- Persist ECU type in SharedPreferences; drop per-connect protocol dialog
- Official-protocol probe and DTC clear on the debug/DTC screens
- Sanity clamp for multi-byte fields; scrollable vertical dashboard
- docs/HANDOFF.md

Includes temporary [DBG]/[KDBG] prints, removed in the next commit.

332dd6209e v1.3.0 — Phase 3: SQLite datalog (DB + recorder + player + providers)
- datalog_session.dart: DatalogSession model with toMap/fromMap, duration helpers
- datalog_db.dart: SQLite schema (sessions + frames tables), batch insertFrames,
  getSessions, getFrames, deleteSession, closeSession
- datalog_recorder.dart: listens to raw frame stream, buffers PendingFrames,
  flushes to DB every 500ms via Timer, finalises session on stop()
- datalog_player.dart: loads StoredFrames from DB, replays at original timing
  adjusted by speed multiplier (0.25x–8x), play/pause/stop/seek, onProgress cb
- datalog_provider.dart: datalogDbProvider, datalogRecorderProvider,
  datalogPlayerProvider singletons; RecordingNotifier (idle/recording state);
  sessionListProvider FutureProvider; PlaybackNotifier with full playback state
- pubspec.yaml: added path ^1.9.0 dependency

11cf7c2b63 v1.0.1 — Phase 1 complete + BT connection test UI
- Phase 1 core protocol: temp_table, neg8, sensor_state, s300_parser,
  kpro_parser, dtc_map, sensor_defs (50/50 tests passing)
- BT layer: bt_service.dart, bt_poller.dart (100ms poll, NEG8 validation)
- Connection test UI: device picker, protocol selector, live sensor screen
  with LIVE DATA + DEBUG LOG tabs
- Runtime BT permission request (Android 12+) + auto-enable Bluetooth
- Android: minSdk=26, all BT+location permissions in manifest
- Fixed flutter_bluetooth_serial namespace for AGP compatibility
