Pull Request Overview
This PR adds support for rebuild branches in the PowerShell CI/CD pipeline. Rebuild branches (e.g., rebuild/v7.4.13-rebuild.5) are used for rebuilding existing releases with packaging or infrastructure fixes. The changes enable these branches to skip LTS package creation and conditionally sign MSIX packages based on whether it's an official build.
Key changes:
- New template
rebuild-branch-check.ymldetects rebuild branches and sets a reusable variable - All platform packaging templates (Windows, macOS, Linux) skip LTS package building for rebuild branches
- MSIX signing becomes conditional based on the
OfficialBuildparameter - Channel selection forces rebuild branches to use the Preview channel
- Deployment script excludes LTS packages for rebuild versions

This pull request introduces improved handling for "rebuild" branches across the build and packaging pipelines. The main goal is to ensure that rebuild branches are not treated as LTS (Long Term Support) releases, and that LTS packages are not built or published from these branches. The changes also add better diagnostics and parameterization for official builds.
Key changes include:
Rebuild Branch Detection and Propagation:
rebuild-branch-check.yml, which detects if the current branch is a rebuild branch and sets an output variable (IsRebuildBranch) for use in other templates and scripts.linux-package-build.yml,mac-package-build.yml,packaging/windows/package.yml, andPowerShell-Coordinated_Packages-Official.yml), ensuring consistent detection across platforms. [1] [2] [3] [4]LTS Handling Adjustments:
IsRebuildBranchvariable before marking a build as LTS or adding LTS packages. [1] [2] [3] [4] [5] [6]Channel and Preview Logic Improvements:
Pipeline Parameterization and Diagnostics:
package-create-msix.ymltemplate to accept anOfficialBuildparameter and only sign MSIX bundles for official builds. Added more verbose logging and a debug step to check variable values during the pipeline. [1] [2] [3] [4]These changes collectively ensure that rebuild branches are handled safely and consistently, preventing accidental LTS releases and improving traceability in the build process.
