perf(ci): native ARM Docker build (drop 90min QEMU emulation)#185
Merged
Conversation
Multi-arch Docker build `platforms: linux/amd64,linux/arm64` on a single x86_64 runner used QEMU to emulate arm64 — Rust + C++ build inside that emulated container takes 5-10× native time. Last release spent 90+ min on the Docker step. Split into per-platform matrix using the free `ubuntu-24.04-arm` runner for arm64. Same pattern as PR #182's release matrix swap. Each platform builds + pushes a `:tag-amd64` / `:tag-arm64` image. A docker-manifest job combines them into the canonical `:tag` and `:latest` multi-arch references via `docker buildx imagetools create`. Expected: 90min → ~10min wall-clock (two ~10min native builds in parallel + ~30s manifest combine). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Resolves conflict in Cargo.toml [workspace.dependencies] where P0a's `fs2 = "0.4"` collided with main's new `[profile.release]` block from the CI-throughput tune (PRs #173/#179/#182/#184/#185/#186 wave). Brings in stale-test fix for `release_workflow_publishes_cli_and_mcp_npm_packages` via PR #173's distribution.rs update (drops origin-darwin-x64 needle).

Multi-arch Docker build with `platforms: linux/amd64,linux/arm64` on x86_64 runner uses QEMU to emulate arm64. Rust + C++ compile under emulation = 5-10× native time. v0.7.0 spent 90+ min on the Docker step. Cancelled and applying fix.
Change
Split into per-platform matrix using free `ubuntu-24.04-arm` for arm64 (same as PR #182's release matrix). Per-platform tags (`:v0.7.0-amd64`, `:v0.7.0-arm64`), then `docker-manifest` job combines them via `docker buildx imagetools create` into canonical `:v0.7.0` and `:latest` multi-arch refs.
Expected: 90min → ~10min wall-clock.
