fix(mobile): serialize native chat PTY writes and fence superseded ask keystrokes (STA-3333) (#12502)
* fix(mobile): serialize native chat PTY writes

Two composed native-chat write sequences into one PTY interleaved their
bytes: the per-terminal send-in-flight guard lived inside the image
attachments hook, so ask answers, permission choices, and question
answers wrote straight past it. Move the guard to a shared module-scope
write lock (the terminal outlives any one screen) and take it on all
four paths.

Ask answers additionally queue behind the prior chain's RPC rather than
racing it, and a superseding answer is fenced once a key has actually
landed: an accepted or ambiguously-delivered keystroke already moved the
remote selector, so a replacement's from-scratch key plan would answer
the wrong question. A superseding answer inherits the cancelled chain's
hold (refcounted, last chain out releases) so changing your mind
mid-answer still works, and Stop/cancel stay unguarded so an interrupt
can never deadlock against the send it cancels.

Refs STA-3333.

* fix(mobile): report a fenced native-chat answer instead of dropping it

The fence added for superseding Ask answers returned false with no
onSendError, and the card re-enables on a false result — so a queued
answer vanished with no banner and no toast, looking exactly like a dead
button. Every other bail in answerAsk reports. Keep the generation-
mismatch branch silent: a newer answer owns the error surface.

Also covers the hold-count release, which had no test at all: replacing
it with an unconditional release left all 58 tests green while silently
reopening the terminal mid-sequence — the exact interleave this PR fixes.

* fix(mobile): stop a superseded answer from clearing the fence banner

A chain that finished its key plan reported `true` even after a newer answer
superseded it. The route sends through useNativeChatAcceptedAction, whose
accepted callback retires the send-error banner — and that callback runs after
the successor's fence report, because finishTurn() fires in `finally`, before
the chain's own promise settles. So the successful predecessor deterministically
wiped the fence message the successor had just raised: every healthy write took
that branch, which made the previous commit's report vacuous exactly where it
mattered.

A superseded chain now reports no success, matching every other supersession
checkpoint in this hook.

* fix(mobile): fence on the turn slot, not the generation counter

The supersession guards added in c36f2ce14e read `generationRef`, but
`cancelPending()` bumps that counter from three callers with no successor
chain: Stop, ask-cancel, and the lease effect that fires on every
disconnect. An answer whose key had already landed then reported false —
`fail()` never runs on an accepted write, so the card stayed up silent
with Submit re-enabled, and the retry wrote the same key into a selector
that key had already advanced.

Test the turn slot instead: a successor takes it synchronously before
its first await and cannot resolve ahead of this chain, so it means
"a successor took over" exactly, without catching bare cancellations.

* fix(mobile): report a fenced answer when a dropped lease bumps the generation

The fence-report guard tested generationRef, which answers "was I
cancelled", not "did a successor replace me". Stop and ask-cancel both
write an Escape that clears the ask card, so their silence is harmless.
A dropped input lease bumps the same counter and writes nothing: the
card stays up with Submit re-enabled while the predecessor's option key
has already advanced the live selector, so the retry double-steps it.

Gate on the turn slot, matching the two success returns.

* test(mobile): cover the turn-slot release after a landed answer

The slot delete in the finally was the one line in this hook no test
killed: without it a landed answer's resolved-false turn stays parked,
so every later answer on that handle reads a fenced predecessor and the
ask card dies after its first use.

* test(mobile): keep PTY write locks terminal-scoped
