android: the handoff — the pending rounds, the pipeline, and what is unverified

Everything written this session that has not been through the device: rounds 43
to 48 (each patch adversarially verified, 43's transient-notice expectation
fixed), a partial round 49, the pipeline scripts, the Android Auto design and
the icon comparison mock. Also the two harness changes that were never A/B'd —
adaptive waits, which may only shorten a declared wait and never lengthen it,
and a ship that runs the mock walk and the deploy at the same time. The A/B and
its 255-step baseline are in handoff/tools; main stays at what the phone has
actually walked.

+android: reorder from the sheet — a playlist row up, down or to the top; a queue row up or down
+
+Without a drag: a playlist row's sheet moves it up, down or to the top and
+persists the whole order in one call (playlist_set_order, as the desktop's
+drop does); a queue row's sheet moves it up or down, never past the track
+playing. Also src-tauri/android/ship.sh — one round end to end: the mock
+walk, the embedded build installed, the phone walk, the commit, each step
+gated on the one before.
