Second merge of #674: the author pushed the thumb-arc handback from the review themselves (e8fc08be), byte-identical in code to the merge-time fix already here, so this brings their round in and keeps the browser test and docs added at merge.

A scroll whose first move past the tap slop leaned sideways (a thumb arc) locked as 'swipe' for the whole contact, and SwipeHandler drops a swipe at 50 px of vertical drift, so the gesture did nothing. Past that limit the drag is now a 'y' scroll. Also brings the mobile-handlers fileoverview to the current 500 ms / 50 px limits and notes in the Mobile Guide that a selection pauses the swipe and a wide terminal pans instead.
Merge-time fix for #674: the first travel past the tap slop decided the
axis for the whole contact, so a scroll that opened on a thumb arc
(+9 px across, +5 px down, then straight down) locked as 'swipe'. Every
later touchmove returned before the scroll code and SwipeHandler gave
the swipe up at its 50 px drift limit, so the gesture did nothing. Past
SwipeHandler.maxVerticalDrift the drag is now handed to 'y' (and the
published axis with it), so it scrolls; a clean sideways swipe, a
vertical scroll and a long-press drag are unchanged.
The source pin in test/session-swipe-gesture.test.ts moves with the
code and also pins the drift value, and a new browser test drives the
real touch listeners: the thumb-arc drag ends as a scroll (it fails
without the fallback, axis stays 'swipe') and a clean sideways swipe
stays a swipe with nothing scrolled. The architecture note and
src/web/CLAUDE.md now say a swipe drag is consumed only up to that
limit.

The terminal's touch handler and the session swipe judged every gesture separately, so a sideways flick also ended as a tap on the session being left (a link, a CLI click, a keyboard toggle) or as a vertical scroll. The terminal now locks the dominant axis past the tap slop, hands a sideways drag it cannot pan to the swipe and publishes the axis, and the swipe stands aside for scrolls, pans, a lift the terminal consumed (its selection gesture), touch selections, a second finger and surfaces with controls of their own. A touch that starts outside the terminal resets the published axis, so swiping from the phone home screen into a session keeps working after a terminal scroll. A deliberate swipe gets 500ms instead of 300ms, and vertical drift cancels it mid-gesture instead of only at the lift.
