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.

+Community's fourth tab is **Taste**: the interests this phone has
+declared to the Soulseek server (`slsk_interests_mine`, `slsk_interest_set`)
+and the people the server ranks as close to them (`slsk_similar_users`), a
+row each into the peer sheet. A like or a hate is a chip and tapping one
+takes it back; "Add a like" and "Add a hate" declare a new one. Every
+declaration asks the server again and the chips stay quiet until it has
+answered, because the ranking only moves when its input does. The lists
+are this client's own — the backend keeps them and re-declares every one
+at login, since the server's copy belongs to the account and another
+client signed in elsewhere can change it under us. Mock-walked only: a
+live sign-in and the server's own ranking are Kyle's to see.
