ci: pilot per-arch split for faster-whisper and llama-cpp-quantization
Convert two backends from QEMU-emulated multi-arch (linux/amd64,linux/arm64
on a single ubuntu-latest) to native per-arch + manifest-list merge:
- amd64 leg on ubuntu-latest
- arm64 leg on ubuntu-24.04-arm (native, ~5-10x faster than emulated)
- merge job assembles both digests under the final tag via
docker buildx imagetools create
Backends piloted:
- -cpu-faster-whisper (small Python, fast baseline)
- -cpu-llama-cpp-quantization (heavier compile path, stress test)
Infrastructure changes that the rest of Phase 2 (Tasks 2.5+) will reuse:
- .github/backend-matrix.yml entries gain a `platform-tag` field
('amd64'/'arm64') for matrix entries that participate in the split.
Other entries omit it; backend_build.yml already defaults missing
values to '' (empty cache key suffix preserved as cache<suffix>-).
- backend.yml + backend_pr.yml forward `platform-tag` from matrix to
the reusable backend_build.yml.
- scripts/changed-backends.js groups filtered entries by tag-suffix
and emits a `merge-matrix` (plus `has-merges`) for groups of size>=2.
Singletons aren't merged.
- backend.yml + backend_pr.yml gain a `backend-merge-jobs` job that
consumes merge-matrix and calls backend_merge.yml after backend-jobs.
PR variant is also event-gated so the no-op-on-PR merge job doesn't
even start.
The other 34 multi-arch entries are unchanged in this PR -- Task 2.5
fans out the same shape to them once the pilot is observed green.
