Two sibling pages that share a title collide on one vault filename, so the
layout appends a cosmetic ` ~<slugId>` suffix (engine disambiguate()). That
suffix is a local filesystem artifact and must never become the page's real
Docmost title, but on ingest the filename-derived title carried it back into
the DB on some paths (observed: intermittent same-title collision left a page
permanently titled "Title ~<slugId>"). Strip it in renamePage() — the single
choke point every git-sync title write funnels through — but only when the
trailing token equals THIS page's own slugId, so a genuine user title that
legitimately ends in ` ~token` is never corrupted (slugId is a random nanoid).
Repro: create two pages with the same title; ~1 in 4 the second page's title
is permanently polluted. After fix: 0/6.
