Android step detector silently returns no events on API 29+
when ACTIVITY_RECOGNITION is ungranted, so cadence was always
absent from recorded tracks. Declare the permission, request
it at GPS start, guard sensor registration and retry it from
MainActivity.onRequestPermissionsResult when the user grants
mid-session, and toast a hint if they deny.
Use Android TYPE_STEP_DETECTOR sensor in LocationForegroundService to
count steps in a 15s rolling window. Cadence (spm) is computed at each
GPS point and stored alongside lat/lng/altitude/speed. Session detail
page shows cadence chart when data is available.
No additional permissions required — step detector is not a restricted
sensor. Gracefully skipped on devices without the sensor.
Recipes from /rezepte now appear in the food search on /fitness/nutrition,
with per-100g nutrition computed server-side from ingredient mappings.
Recipe results are boosted above BLS/USDA/OFF in search ranking.
OpenFoodFacts products are now searchable by name/brand via MongoDB
text index, alongside the existing barcode lookup.
Recipe and OFF queries run in parallel with in-memory BLS/USDA scans.
Wraps the web app in a Tauri Android shell that provides native GPS
via the geolocation plugin. Includes foreground service for background
tracking, live map display, GPS data storage in workout sessions,
and route visualization in workout history.
