Advance the version once from the released 0.2.0 base and publish the
matching changelog. No transfer, protocol or storage behaviour changed,
so the store description stands.

The dashboard screenshot prints BuildConfig.VERSION_NAME, so it is the
one store image a version bump invalidates. Recaptured on the same
1080x2400 profile with the same demo state.

Document the multi-remote release, publish matching store metadata,
and advance the version once from the released 0.1.3 base.

versionCode 4. Bound the SSH handshake so a stalled server cannot hang
a sync. Persist config, key, and host pin atomically so an interrupted
write cannot corrupt state. Replace the chained one-time jobs with
periodic work that survives reboots; the schedule floor is now
WorkManager's 15-minute minimum.

Persist config, key blob, and host pin via AtomicFile so an
interrupted write cannot corrupt state. Validate the port, clear the
host pin when the remote changes, cap imported key size, time out
native helpers, and escalate rsync termination to destroyForcibly.
Serialize manual and scheduled syncs behind a mutex.

Replace the chained one-time jobs with plain periodic work: it
survives reboots without a boot receiver and cannot silently die
like a broken chain. Costs the sub-15-minute interval, which photo
backup does not need. Document the floor and that syncs run on any
unmetered network, not only WiFi.

versionCode 3. Drop --mkpath so remotes with an rsync older than 3.2.3
(stock macOS included) can receive syncs; rsync still creates the final
remote path component on its own. NDK host toolchain detection so the
native build also runs on macOS hosts.

versionCode 2. Empty-path and config-corruption fixes, rsync process
cleanup on stopped syncs, keygen error reporting, and the store icon.

The app ships only an adaptive vector launcher icon, which F-Droid
cannot render, so the store listing showed no icon. Ship a 512x512
raster of the same mark where F-Droid looks for it (fastlane images/
icon.png).

A small Android app for one-way folder backup, a KISS alternative to
Syncthing. It bundles rsync (built from pinned source via the NDK) and
a pure-Go SSH transport, both shipped in the APK as lib*.so and run from
the native library directory.

rsend pins the host key, stores the ed25519 identity Keystore-encrypted,
pushes each folder additively or as a mirror, and runs on demand or on a
WiFi-only schedule. The build is self-contained and reproducible: make
setup provisions the toolchain, make builds rsync, rsh, and the APK.
