Capture the 2026-06-26 lessons durably: ship via the hardened publish
script only, v1+v2+v3 signing is enforced by apksigner (AGP ignores
enableV1Signing at minSdk>=24), diagnose install failures with adb
install FIRST, signature-key changes force a one-time uninstall, and
keep all phone/adb work scoped to com.archipelago.app.debug.
