Back at the root was calling SystemNavigator.pop(). That is not "background
the app": on Android it calls finish() on the activity, which tears down the
Flutter engine and drops the radio connection. Backing out and reopening
therefore landed on a disconnected radio needing a fresh connect. Wrong call
for the job, and worse than the behaviour it replaced.
Backgrounding without finishing needs moveTaskToBack, which has no Flutter
equivalent, so it goes over a method channel:
- MainActivity exposes meshcore_open/app_lifecycle with a moveTaskToBack
method, alongside the existing USB channel.
- AppBackgrounder wraps it and is a no-op off Android, where programmatic
backgrounding either does not apply (desktop windows close by their own
chrome) or is forbidden (iOS). On those platforms back at the root stays
unhandled rather than doing something destructive.
- AppShell awaits it instead of calling SystemNavigator.pop().
The activity stays alive, so the connection survives and reopening returns to
where the user was.
flutter analyze clean, dart format clean, 469 tests pass.
Bound ACCESS_FINE_LOCATION and ACCESS_COARSE_LOCATION to maxSdkVersion=30,
mirroring the already-bounded BLUETOOTH/BLUETOOTH_ADMIN. On Android 12+ the
app scans with BLUETOOTH_SCAN + neverForLocation and reads no phone location
(no location dependency or API usage in lib/), so location is only needed for
legacy scanning on API <=30. Cleaner permission profile + Data Safety story
for the Play submission (#159).
Epic #210. Test gate #212 (closed-beta hardware validation).

Freeze permanent applicationId/bundle id to app.offband.meshcore
(three-segment so app.offband.* reserves the brand family; a future
app.offband.meshtastic won't collide).
Display name "Offband Meshcore" across: Android android:label, iOS
CFBundleDisplayName, Windows + Linux window titles, MaterialApp title,
Windows VERSIONINFO (ProductName/FileDescription/CompanyName), pubspec
description, GPX creator. iOS/macOS bundle ids + Linux APPLICATION_ID
set to app.offband.meshcore.
Version 9.0.0+12 -> 9.0.1+13 (PATCH milestone + build).
Deferred (unchanged): internal Dart package name (meshcore_open imports),
Android namespace + MainActivity package, exe/bundle filenames, docs prose
(README/privacy/documentation still say MeshCore Open - separate sweep).
MIT attribution to zjs81/MeshCore preserved (LICENSE untouched).
Verified: flutter analyze clean; Android debug APK built green;
aapt2 dump packagename = app.offband.meshcore; Windows compiled clean.
