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.

+<!-- The night half of the API 31+ splash, and it is not a duplicate for
+     tidiness. The resource qualifier order puts NIGHT MODE ahead of PLATFORM
+     VERSION, so on a dark-mode Android 12+ phone the generated
+     values-night/themes.xml beats values-v31/themes.xml, Theme.app comes back
+     with nothing on it and the splash is silently ignored — which on this
+     phone means always. Same parent, so the same items.
+
+     ANYTHING ADDED TO THE GENERATED values/themes.xml MUST BE ADDED HERE TOO.
+
+     Theme.App.Starting itself is declared once, in values-v31/themes.xml: it
+     carries no night qualifier, so it matches a night device too. -->
