GPX export: button in session detail, standard GPX 1.1 format.
Background GPS fixes:
- Native service: batched writes (10s flush) instead of per-point
appendText — eliminates race condition with reader
- JS reader: skip corrupt lines, sort by timestamp, track by ts
instead of line count — handles partial writes and reordering
- Recovery: idempotent import using max DB timestamp
- Live recording: seq numbers on every point
- FileObserver watches correct path (app root, not files/dev.baldav.app)
- Removed ACCESS_BACKGROUND_LOCATION (causes throttling)
Nav: "Трекинг" button on GPS screen when recording active.
Products seed: 9299 products bundled in products_seed.db, Kotlin
copies from assets to filesDir on Android, Rust imports into main
DB on first launch with version check for future updates.
Settings: profile button, offline toggle, GPS permission, app info
with git hash and build date from build.rs.
Build: version synced to Cargo.toml, unified import (GPX/FTB by
extension), chart zoom Ctrl+scroll only, scroll wheel zoom disabled
on detail map.
