* fix(mobile): harden terminal height refit (follow-up to #8647)
Addresses review feedback on #8647:
- Defer height refits while the keyboard is visible and coalesce every
skipped layout change into one correction after the keyboard closes,
via a pure reducer. Prevents an over-fit that settles with the keyboard
up from surviving (on iOS the edge-to-edge keyboard doesn't change the
frame height on close, so there was no later event to re-trigger it).
- Drive height layout callbacks imperatively (notifyTerminalFrameHeight)
instead of setState, so height-only layout bursts no longer re-render
SessionScreen.
- Cache the updateViewport capability (method_not_found -> unsupported):
old desktops now get one unsupported probe then legacy resubscribe,
instead of one probe per refit. Reconnect resets the cache so an
upgraded desktop is re-detected.
No server schema or subscription-protocol changes; desktop-first stays
compatible.
Tests: 703 mobile terminal/session pass; tsc, oxlint, formatting clean.
* fix(mobile): re-check keyboard when a deferred height refit fires
Close a race in the keyboard-deferral: a height refit deferred at
keyboard-close arms a 150ms debounce timer, and if the keyboard reopens
inside that window the timer still fired and reflowed the PTY mid-keystroke.
The timer callback now re-consults the reducer (new `refit-committed`
event) when the armed refit is height-originated: if the keyboard is
visible again it re-defers (pending) instead of reflowing, and runs on the
next keyboard close. Scoped via a height-originated flag so width/rotation
and the forced reconnect/foreground re-asserts stay unguarded and always run.
Tests: reducer coverage for the reopen-during-debounce re-defer + a wiring
assertion; 705 mobile terminal/session pass; tsc, oxlint clean.
