Subject: Android wrapper app (android/): a minimal TWA around v3.coinos.io
 whose whole reason to exist is intent registration —
 lightning:/bitcoin:/nostr:/lnurl:/lnurlw:/lnurlp: VIEW intents and the same
 schemes via NFC NDEF dispatch (bolt cards, address stickers; NFC declared
 required=false), plus verified https links to the site. LauncherActivity
 forwards a scheme URI into the web app as ?u=<encoded>; the web app reads it
 BEFORE features construct — a nostr npub/nprofile rewrites itself onto the
 existing /npub profile deep link, payment URIs stash and dispatch through
 handleScanned (the QR path) once a wallet is open, and the param is stripped
 from the URL either way. assetlinks.json (static/.well-known/, copied by
 build.js) vouches for the signing cert so the TWA runs URL-bar-less; the
 built APK is served at /coinos.apk for sideloading. Signing keystore lives in
 android/ GITIGNORED (keystore.properties beside it) — the assetlinks
 fingerprint pins it, so losing it means re-shipping assetlinks too. Verified:
 headless ?u= routing (lightning → Send with invoice filled + URL cleaned;
 nostr → profile page), APK installed on a real phone via adb, schemes
 registered (chooser appears where other wallets also claim lightning:)
