chore(config): blocking client-test gate in pre-push (T-1065); amend D-067 chime duration

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.

+- **Amendment (2026-06-12):** **Chime duration is 800 ms**, not 300–400 ms. The shipped `sfx_monologue_chime.ogg` is a deliberate 0.8 s manual synthesis (Sprint 10, #327; full synthesis spec in `docs/assets/audio/ui.md` UI-005) and the client test suite pins the catalog duration (`test_audio_sprint13.gd`). The onset timing, "unresolved" character, and recognition sequence above are unchanged — only the duration figure was stale. Surfaced by the T-938 test-debt fix.
