Fix CI: lint line-length, lockfile detached HEAD, release disk exhaustion

- quality.py:122: split long tuple line to satisfy E501 (146 → ≤120)
- update-lockfile.yml: add branches filter so tag pushes don't trigger
  the workflow (tag checkout is detached HEAD; git push has no target)
- release.yml: split four Docker build steps into parallel jobs (build-gpu,
  build-cpu, build-rocm, build-intel), each with its own runner; previously
  all four ran in one job and exhausted disk after GPU+CPU builds, leaving
  ROCm and Intel cancelled
