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: hours on the library's count line, By format, Jump back in on the empty search

+The desktop Library summary's hours on the phone's count line; a By format
+order from the file stats (lossless by depth and rate first, then by
+bitrate, the badge as the card's line); the empty Search page's Jump back
+in — the last records played — as the desktop's empty search shows them.
