* Implement Phase 2 of the sync protocol using a self-describing JSON format (`VALUES_JSON`) to synchronize all measurement types, including custom ones. * Add a snackbar notification in `SharedViewModel` to prompt the user to open the sync app if it is installed but unreachable (e.g., force-stopped). * Introduce coalesced "changed" sync triggers for bulk import and backup restore operations to improve efficiency and prevent foreground service spam. * Update sync intents and `DatabaseProvider` to include `userId` and measurement IDs for better multi-user routing and bidirectional synchronization. * Implement measurement deletion support in `DatabaseProvider` via timestamp matching. * Bump sync API version to 2.
I added the values for my Beurer BF450 scale in BeurerSanitasHandler.kt and it worked
* feat: Add support for Taylor 5331891 BIA Scale Adds TaylorBIAHandler for the Taylor Body Composition Bathroom Scale (advertised as "5331891 BIA Scale"). The scale exposes service 0xFFB0 (FFB1 write, FFB2 notify), the same GATT layout as the MGB family, so MGBHandler previously mis-claimed it and the session timed out with no measurement because the notification format differs. Protocol (reverse-engineered from btsnoop HCI logs): - 20-byte NOTIFY frames "AC 27 <flag> <chan> <hi> <lo> ... 24 D5 <cksum>". - weight_kg = (((chan & 0x01) << 16) | (hi << 8) | lo) / 1000.0, where the channel byte's low bit is weight bit 16 (0x8C < 65.536 kg, 0x8D >= 65.536 kg). - flag 0x80 = stable, 0x01 = summary record. Verified against two captures (171.2 lb and 173.0 lb readings). The scale transmits weight only; body composition is computed app-side by the vendor and is not exposed over BLE, so only LIVE_WEIGHT_STREAM is implemented. TaylorBIAHandler is registered ahead of MGBHandler in ScaleFactory (first non-null supportFor wins). Includes unit tests for the weight decode.

The previous code published only via a flat fallback timer, which could capture a still-settling value. Publish instead when the same weight repeats STABLE_FRAMES (4) times in a row (~1s at the scale's ~4Hz stream) — the settled value repeats verbatim while step-on ramp values are all distinct. Explicit stable/summary frames are still honored, and a last-resort timer (FALLBACK_DELAY_MS) covers weight that never settles. Verified on device: records 77.65 kg = 171.2 lb.

* Simplify `supportFor` by removing the service UUID check and relying solely on device name matching.
