* test(producer): add parallel capture regression test

Add a regression fixture that forces workers: 2, ensuring the parallel
capture code path (browser-per-worker in BeginFrame mode) is exercised
in CI. All existing fixtures pin workers: 1, so this is the first test
that would catch a regression in the multi-worker pool isolation fix
from PR #1087.

The composition is 5s @ 30fps (150 frames), which exceeds both
MIN_FRAMES_PER_WORKER * 2 (60) and minParallelFrames (120), so the
parallel coordinator will always split work across workers.

Baseline output/output.mp4 must be generated inside Dockerfile.test
before the fixture can run in CI.

* test(producer): bump parallel capture test to 4 workers

Matches realistic auto-mode worker counts (4-6 on typical machines),
not just the minimum (2) that triggers the bug.

* test(producer): add golden baseline for parallel capture regression

Generated inside Dockerfile.test on amd64 Linux (Docker image
hyperframes-producer:test) to match the CI rendering environment.

* test(producer): address review feedback on parallel capture test

- Add fixture to shard-5 in regression.yml so CI actually runs it
- Reframe description: multi-worker path coverage (frame distribution,
  reorder buffer, per-worker browser lifecycle), not GPU-specific crash
  guard — SwiftShader CI can't reproduce the hardware compositor race
- Remove dead @keyframes count-up (content doesn't apply to div)
- Remove unused CSS animation reference on .counter
- Regenerate golden baseline with cleaned-up HTML

* fix(producer): replace rAF + CSS keyframes with GSAP in parallel-capture test

The composition used requestAnimationFrame for a frame counter and CSS
@keyframes for animations, which triggered screenshot capture mode
(non-deterministic across workers) and caused 29 PSNR failures in CI.
All animations now use the GSAP timeline, keeping the render in
deterministic BeginFrame mode. Baseline regenerated in Docker.
