- Install expo-auth-session + expo-web-browser
- Add 'bincio-rec' URL scheme to app.json for deep-link redirect
- auth.ts: generate PKCE verifier/challenge, open bincio.org/oauth2/authorize
in browser, exchange auth code for RS256 id_token, store in AsyncStorage
- SettingsScreen: remove handle/password fields, single 'Sign in with bincio'
button that opens the browser flow
Sets up the full bincio-rec source tree: Zustand recording store with
haversine stats, background GPS via expo-task-manager, BLE scan/subscribe
for HR and power, GPX writer with Garmin extensions, SQLite recordings
list, multipart upload to bincio-activity, React Navigation stack with
bottom tabs, and build instructions in README.md.
