android: the faces the walk had never seen — six failure states, read back in their own words

Round thirty-one gave the phone honest error states and shipped six of them
unobserved, because neither `loadHome` nor `loadLyrics` was reachable from the
`__ss` handle and both answer a second ask with nothing. The handle carries the
two stores and their two loaders now, and a block of mock steps arms each
failure with the mock's own weather, drives the face, and asserts the sentence
a person reads as well as the absence of the Rust string behind it: Home's
catalog line, the Gaps line and its second tap, a catalog record's stub, the
artist page's two different answers, a playlist that would not read, the lyrics
lookup that failed, a refused transfer, and the library toast's Try again,
pressed for the first time.

It sits before the first-run block, which reloads and empties the mock's
follows; every failure is disarmed by the step that proves the face heals, and
a last step asserts nothing was left armed. The phone walk gets a safe step of
its own — a terminal transfer row written into the store and taken away,
nothing fetched and nothing reaching the shade. ANDROID.md now names what the
walk still cannot see: three screens that draw a raw backend string, six error
faces with no expectation, and the history mirror printed on every step and
asserted on none.
