Addresses the review on #244.
BLOCKING (item 1). selectSession() ends with scrollToLastNonEmptyLine(), which
parks the viewport above the bottom for any session taller than the screen, so
after a tab switch every tap classified as 'history' — touchstart ran
preventDefault() + blur, and touchend's early return skipped focus. Both routes
to focus closed on one gesture, the same mechanism as #173.
Suppressing the mouse REPORT while scrolled up is right and is kept; suppressing
FOCUS is not. touchstart now only preventDefaults 'content' taps (a scrolled-up
viewport sends nothing, so there is no compatibility click worth cancelling), and
the 'history' branch focuses instead of blurring.
Verified against the maintainer's own test, which was already on master and red:
`keeps the terminal input focusable after a tab switch parks the viewport
off-bottom` fails without this change and passes with it.
Item 2: dropped both `terminal-action-pending` guards. The class exists nowhere
in the repo, so both branches were permanently false and the comment promised
coverage that did not exist.
Item 3: removed the `Working` literals. Live claude 2.1.226 prints
"Cooked for 2m 6s" with a different bullet and a randomised verb, so they were
dead code. The status row is matched by its affordance ("esc to interrupt")
instead, which is what makes it actionable. The affordance regex is also
tightened to require a key or gesture name, so prose like "click here to open
the file" no longer dismisses the keyboard.
Item 4: removed _shouldForwardTouchScrollToApp and its test. It was never called,
and wiring it as written would have restricted forwarding to claude only,
dropping gemini from the path #205 established — a behaviour change this PR has
no reason to make.
Smaller items: the touchstart classification is cached and reused for the
touchend of the same gesture (keyed on exact coordinates, so a moved finger
re-classifies), removing two of the three full-viewport scans per gesture; the
duplicated touchLastX assignment is gone; and the no-touch bail-out returns null
rather than claiming 'history'.
test/mobile/keyboard.test.ts: 51 tests, 5 failed | 46 passed — the same 5
pre-existing failures as master, unchanged.
