pre-push now runs the full gdUnit4 suite via tests/run-godot when client/
changed — blocking, ~100s, suite made green by T-973 and independently
re-verified. The tooling gate (make test-tooling on TOOLING_CHANGED, T-1066)
rides in the same hook. D-067 amended: the shipped chime is a deliberate
800ms synthesis (#327, ui.md UI-005); prose said 300-400ms. Ticket closes
for the maintenance wave in the changelog.
