Run macOS native tests and release-profile checks on shared runners while retaining required status contexts. Preserve target cache identities and reuse source downloads within each runner.
Use pinned nextest for full native tests while retaining doctests, production-feature checks and both macOS release checks.
Publish shared dependency snapshots from successful default-branch runs, keep compiled artifacts architecture-specific, and preserve cross-process exclusion for shared theme fixtures.
Run the full platform matrix for both draft and ready pull requests without repeating it for readiness-only transitions.
