Pull request overview
This PR narrows when the Installer_Build_And_Test Helix jobs run in eng/pipelines/runtime.yml, so installer validation is triggered primarily by installer-relevant path changes, while keeping osx_arm64 installer tests running on CoreCLR changes to help catch single-file issues.
Changes:
- Updated installer Helix job conditions from
non_mono_and_wasm.containsChangetoinstaller.containsChangefor most installer platforms. - Split out osx_arm64 installer testing into its own block, triggered by
coreclr.containsChangeORinstaller.containsChangeOR rolling builds. - Removed osx_arm64 from the general (windows_x64/linux_x64) installer job platform list.

Change Installer_Build_And_Test job conditions from non_mono_and_wasm.containsChange to installer.containsChange for most platforms. Previously, installer helix tests (5 platforms) ran on any non-mono change including pure coreclr or libraries changes. Split osx_arm64 into its own block with a broader condition that also includes coreclr.containsChange, per Elinor Fung's guidance that Mac ARM64 is most likely to catch single-file issues from coreclr changes. - windows_x86, osx_x64: installer OR rolling only - windows_x64, linux_x64: installer OR rolling only - osx_arm64: coreclr OR installer OR rolling Saves 4 helix jobs on coreclr-only PRs (was 5, now 1 remains). Saves 5 helix jobs on libraries-only PRs. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Summary
Scope the
Installer_Build_And_Testhelix jobs to only run when installer-relevant paths change, instead of on any non-mono/non-wasm change. Previously these 5 helix jobs ran on every coreclr and libraries PR even though installer tests (host+packs) are unaffected by JIT, GC, or library code changes.Exception: osx_arm64 retains a broader trigger that also includes
coreclr.containsChange, per @elinor-fung's guidance that Mac ARM64 installer tests are most likely to catch single-file issues from coreclr changes.Changes

The
