ci: speed up release build with sccache + single cargo invocation#56
Conversation
- Combine 4 per-bin cargo invocations into one --bin x --bin y call to avoid redundant workspace resolution and linking. - Add mozilla-actions/sccache-action with GHA backend for cross-branch rustc output caching. - Set CARGO_INCREMENTAL=0 for smaller, more reusable release caches. - Print sccache stats post-build to monitor hit rate.

Summary
cargo buildcalls into one multi---bininvocation to drop redundant workspace resolution/linking.mozilla-actions/sccache-actionwith GHA backend; stacks on top of existingsetup-rust-toolchaincache (registry/target) for cross-branch rustc-output caching.CARGO_INCREMENTAL=0for smaller, more reusable release caches.sccache --show-statspost-build for hit-rate visibility.Motivated by slow Windows jobs in recent release runs (linker-bound on msvc).
Build artifact
Add the
build-artifactlabel on this PR to trigger the release workflow and validate end-to-end on all 4 targets (linux-gnu, linux-musl, macos-arm64, windows-msvc). Checksccache --show-statsin the first run (expect misses) and a second re-run (expect hits) to confirm caching works.Test plan
