A fork's About rail says how far its default branch sits from its parent's, beside the Update from parent button, and offers the update only when it would fast-forward. Built by the crew on the forge, reviewed and merged there, proposed here as one change.

Read how far a fork has drifted from its parent 3a2a54daab

`forkDrift` answers what `syncFork` would do before anyone presses the
button: `behind` is what an update would bring, `ahead` is what makes one
impossible. It is a read, not a mutation — the parent's objects reach the
fork through its alternates, so one `rev-list --left-right --count`
(`divergence`, already in git/branches.ts) in the fork answers both halves,
and both are null when git cannot answer.

Say the distance beside Update from parent 5741ba4987

The Fork-of row now reads "3 commits behind", "up to date", or "1 commit of
its own, 2 behind — merge by hand", and the button appears only when the
update would fast-forward: nothing to take, or commits of the fork's own in
the way, and there is no button to press. The drift is git, so it is read in
`repoHome` and handed to `aboutCard`; the lineage lookup both need is now
`forkParent`.

Read a fork's page behind, current and diverged 7de92624a8

Three states through the real page: dan's fork level with alice's, then
behind by one after she moves on with nothing following her, then bob's,
which has a commit of its own and cannot be updated at all.

The fixture's git environment also clears `GIT_CONFIG_COUNT`, for the same
reason it points the global and system config at /dev/null: a crew run hands
git an `http.extraHeader` for its own forge, and that credential would go to
the test server instead of the one in the clone URL.

🔴 check is red at 6d52ec55da (fix round 1/3). Fix it on this branch: run bun run check locally (lint, typecheck, build, tests, design conformance — the same job CI runs), push, and the review resumes when it is green. The head on origin is what gets reviewed.
