ci: skip Release and its helper for test-only pull requests - #13122

Conversation
release-build compiles the universal Release app from scratch on a macOS 26 runner, about 35 minutes per run. It builds only the cmux target, so a change limited to cmuxTests, cmuxUITests or a package's Tests directory cannot alter what it produces. The router gains a release_build output. It is true whenever a macOS-relevant path outside those test directories changed, and whenever every area is forced. release-build gates on it; the other macOS jobs still gate on macos. A new test file also edits project.pbxproj, so it still runs the Release build. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

release-build now needs both routes: the change must reach the Release build, and the run must be a full-suite run. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

When a Release-relevant file is renamed into one of these test directories, git diff --name-only reports only the destination path. This classifier therefore treats the entire rename as test-only, even though removing or relocating the production source can break the Release configuration. The Release build is then skipped, allowing Release-only failures to reach main. Collect both sides of renames, such as with --no-renames, or otherwise classify the source path too.

Summary
Test-source-only pull requests cannot change the universal Release app, but CI spends roughly 34–36 minutes compiling it and also builds a universal Ghostty CLI artifact solely for that Release job.
Route both the Release app build and its helper work through
release_build. Changes limited tocmuxTests/,cmuxUITests/, orPackages/*/*/Tests/skip Release and the helper's SDK-15 setup, Zig installation/cache, compilation, and uploads. App-host compile admission, all six app-host shards, package testing, and runtime regressions retain their existing routing. When Release is required, the helper retains its SDK/architecture checks and upload retry.The router remains conservative: app inputs, unknown inputs, workflow/router changes, unreadable diffs, and forced events run Release. Any
project.pbxprojedit also runs Release, including edits that only wire a new test file. This does not skip the entire package job; affected-package selection is covered separately by #13118.The required
ci-statusalready accepts a skipped Release job. No app runtime behavior or test assertions change.Validation
git diff --checkpass for the consolidated workflow.swift-package-tests; these routing changes do not claim to fix that test failure. Hosted validation of the new head is pending.Related: #13095, #6134.
