Two concrete root causes for the eternal "Waiting for Amber…":
1. setPackageName could hang forever on GrapheneOS. getPlugin() awaited it with
no timeout, so getPublicKey() (and its 90s timeout) was never even reached.
Now setPackageName races a 3s timeout and continues regardless — the Amber
package is passed explicitly on every call anyway, so it's non-essential.
2. AndroidManifest.xml had no <queries> block. On Android 11+/GrapheneOS the OS
silently blocks the nostrsigner intent without it, so Amber never opens. Added
scripts/inject-amber-queries.mjs (idempotent) and wired it into android:init /
android:sync / android:build so the block is guaranteed present in every APK,
surviving cap sync regeneration.
Bump version to 1.1.9.
