Merge-time fix for #664 (optional item): the drag-and-momentum test
for xterm's own SGR mouse tracking sits in its own describe, nested so
it keeps the file's page and touch dispatcher, and the file overview
mentions it.

Review of #527 (Ark0N, 2026-10-11):
1. A slow touch drag paged a full screen per line. touchmove calls the
fallback once per whole cell, so a slow drag's calls were further apart
than the 150 ms gesture gap and each pre-paid a page (12 lines at 170 ms
sent 12 PageUps). The touch paths now tag every call, touchmove and
momentum frames alike, with a per-contact touchId (incremented on
touchstart), and pageKeysForGesture never splits a contact by time; a
new contact is a new gesture.
2. A pre-paid debt now survives up to PAGE_KEY_DEBT_MS (1 s) of quiet when
the next event goes the same way, so slow small wheel ticks (40 px every
250 ms, a Firefox 1-line notch) pay it back instead of each pre-paying.
A reversal inside the gap (or inside one contact) drops the debt and
accumulates without pre-paying, so a +/-3 px wobble no longer pages
back and forth. A reversal after the gap still pages at once. Main pane
and tiles share the helper, so both get it.
3. A wheel consumed by the dialog check now logs page-keys-dialog-open.
4. The Dashboard wiki names newer Codex beside OpenCode; the invariants
paragraph describes the new gesture boundaries.
Tests: unit regressions through the real _maybePageCliTranscript, helper
cases, tile/main parity for ticks and wobble, and a Chromium test that
drives the real initTerminal touch listeners (12 PageUps before, 1 after).
