jpmschweitzerandClaude Opus 4.8 9a5f5b2ab5 build(hooks): widen pre-push fast path to test/ci/.githooks + guard test (T-393)
The fast-path regex matched only `^(lib/|pubspec\.)`, so a push that ONLY
changed a test, a ci/ gate script, or the pre-push hook itself skipped the
entire ~2min suite — exactly the paths most able to break the suite or the
gate went unchecked. Widen the trigger to include test/, ci/, and
.githooks/, and extract it to a single `trigger_re` variable. Also drop the
header comment's false claim that "release CI runs it forced on a tagged
version" — there is no release CI.

Add test/tooling/pre_push_hook_test.dart: it reads the live trigger_re from
the hook and asserts the load-bearing dirs force the full gate while
docs/assets ride along — so the regex can't be silently narrowed again.

/// T-393: guard the pre-push fast-path classifier.

/// The hook runs the full ~2min gate only when the pushed diff touches a
/// "trigger" path; everything else rides along on the next triggering push.
/// The regex once matched ONLY `lib/` + `pubspec.*`, so a push that ONLY
/// changed a test, a ci/ gate script, or the hook itself skipped the entire
/// suite. This test reads the live `trigger_re` from `.githooks/pre-push` (the
/// single source of truth) and asserts the load-bearing dirs force the gate, so
/// the regex can't be silently narrowed back.
