Long-press opens the message action sheet (#166), but on iOS the system
takes a long-press for itself: the link/image callout or the text-selection
loupe races the 450 ms press. Message rows on touch screens now carry
data-touch-actions (no -webkit-touch-callout), and the pressed row carries
data-pressing from touch-down until the finger lifts, which turns text
selection off for that moment only. Copy Text stays in the sheet.

On coarse-pointer devices the hover action bar is unreachable and iOS Safari
has no contextmenu on long-press. useLongPress (450 ms, < 10 px movement,
cancelled by scroll/lift) now opens an ActionSheet — slides up from the
bottom, drag handle, swipe-down or backdrop tap to dismiss — with the quick
reactions row + 'Add reaction' on top and the same folds Menu the desktop
popout uses (extracted to a shared menuJSX) beneath. Android's contextmenu
echo of the same press is dropped; the press-induced text/image selection is
cleared; the finger-lift's synthetic click is swallowed so it can't hit a menu
item; the sheet ignores 'outside' clicks for its first 600 ms. Desktop is
unchanged (right-click → anchored popout).
Verified with Playwright touch emulation (Pixel 7, CDP touch events):
long-press → sheet with 👍 / Add Reaction / Reply / Forward / Bookmark /
Remind Me / Reply in Thread / Copy Link / Pin / Delete; swipe-down dismisses;
a scroll gesture does not open it; tapping Reply closes it and arms the
composer. Still wants a real iPhone + Android pass before it's called done.
