Tom Boucher 1d208e5af6 test(#3144): bound the git/worktree cluster onto the process seam (#3152)
* test(#3144): bound the git/worktree cluster onto the process seam

Migrates 180 unbounded sync spawn sites across 19 files. Every previously
unbounded call now carries an explicit timeout with a comment giving the
number and why.

The migration is not a callee swap. execSync and execFileSync throw on a
non-zero exit and the seam never does, so each site was classified first:
sites that rely on the throw route to gitOrThrow, and sites that already read
.status to detect an EXPECTED non-zero -- an intended cherry-pick conflict, a
rev-parse outside a repo driving a skip -- route to the never-throwing runGit
instead, which would otherwise throw on exactly the exit being probed for.

Two same-named git() helpers in worktree-cleanup.test.cjs have different
return contracts, one trimmed and one raw; both are preserved rather than
unified.

Collapses five hand-rolled throw wrappers onto one throwIfFailed in
git-fixture.cjs, which gitOrThrow now also uses so the shape cannot drift.

Allowlist drops 139 to 120; BASELINE lowered to match.

* test(#3144): fix pre-PR review findings

Documents throwIfFailed in the CONTEXT.md glossary and CONTRIBUTING.md --
it became the shared throw mechanism without either doc naming it.

Routes the sixth and seventh hand-rolled copies of the throw shape through
throwIfFailed (worktree-baseref-install, worktree-safety-reap); the first
consolidation missed both.

Converts ci-rebase-check's 8 fixture-setup calls from unchecked runGit to
gitOrThrow so a failed setup step aborts where it fails rather than
surfacing later as a confusing failure against the wrong subject.

Adds 12 direct unit tests for throwIfFailed, which until now was only
exercised transitively.

Splits verify.test.cjs's non-git grep/sed bound off GIT_TIMEOUT_MS.

* Bug #3657: verify-reapply-patches false-fails when gsd-pristine/ snapshot is
* newer than backup-meta baseline.
*
* Root cause: the verifier computes user-added lines as
* diff(backup, pristine_on_disk)
* but pristine_on_disk is from a LATER GSD version than the one captured in
* backup-meta.json.pristine_hashes. Lines present in the backup but removed by
* the upstream update appear as "user-added lines that must survive", causing
* FAIL_USER_LINES_MISSING false positives even when the user's real
* customisation survived the merge.
*
* Fix: when backup-meta.json contains `pristine_hashes` and the on-disk
* pristine file's SHA-256 does NOT match the recorded hash, the verifier must
* skip the stale pristine and fall back to the over-broad mode (treating every
* significant backup line as required) rather than computing a diff against the
* wrong baseline. Over-broad mode still passes if all backup lines are present
* in the installed file — it never false-fails for a DIFFERENT reason.
*
* Per CONTRIBUTING.md testing standard: assert on typed structured fields from
* the --json report and the REASON frozen enum. Zero regex / String#includes on
