ci: add matrix skeleton to headless-smoke jobs (#540)#579
Merged
Conversation
Introduces a single-cell `strategy.matrix` stanza on all four smoke jobs (safari / flutter / native / webview). The baseline cell is still `macos-latest`, so behaviour is unchanged today — but future expansion (macos-14, macos-15, macos-16; later Xcode / device / Flutter-version dimensions) becomes a one-line append to `matrix.os` rather than a full job duplication. `fail-fast: false` ensures one flaky cell cannot kill sibling cells once the matrix grows. Leaves the name: field unchanged — GitHub auto-appends the matrix value so the effective check name remains the same until a second cell lands. Refs: #540 (acceptance-criteria Matrix section) + #574 Verified: - `python3 -c "import yaml; yaml.safe_load(open('.github/workflows/headless-smoke.yml'))"`. - Diff only touches the four job headers; no step logic moved.

Code review: P0=0, P1=0, P2=0. Trivial matrix scaffolding. Functionally identical to prior runs-on. LGTM.

Summary
Adds a single-cell `strategy.matrix` stanza to all four smoke jobs (safari / flutter / native / webview) in `.github/workflows/headless-smoke.yml`.
Refs: #540 (acceptance-criteria Matrix section) + #574 (cross-Xcode matrix child issue).
Why
Epic #540's Matrix section requires green runs across macOS 14/15/16, Xcode 15/16/17/26, iPhone 15/16/17/Pro/iPad, and Flutter 3.x/4.x. Each dimension will be rolled out as runner images become available. Landing the skeleton now means the rollout is a one-line append to `matrix.os` (or a new matrix dimension) rather than a full job duplication.
Why one cell now, more later
Adding additional cells (macos-14, macos-15, macos-16) before the runner images are proven stable would keep the cron red and reset the 30-day green countdown in the epic's closing rule. Child issue #574 tracks the staged rollout.
