Pull request overview
This PR backports critical rebuild branch detection and handling improvements from the main branch (#26415) to the release/v7.6 LTS branch. The changes add safety checks to prevent accidental LTS package creation from rebuild branches (e.g., rebuild/v7.4.13-rebuild.5) and implement conditional MSIX signing based on build type. This is essential infrastructure for managing rebuild workflows that shouldn't be treated as official LTS releases.
Key changes include:
- New
rebuild-branch-check.ymltemplate for consistent rebuild branch detection across all platforms - Enhanced LTS package logic that excludes rebuild branches from LTS package creation
- Conditional MSIX signing that only occurs for official builds
- Improved diagnostic logging throughout the pipeline templates

Impact
REQUIRED: Choose either Tooling Impact or Customer Impact (or both). At least one checkbox must be selected.
Tooling Impact
This backports critical rebuild branch detection and handling improvements to prevent accidental LTS releases from rebuild branches. Includes conditional MSIX signing and enhanced pipeline diagnostics.
Customer Impact
Regression
REQUIRED: Check exactly one box.
This is not a regression.
Testing
Original PR added comprehensive rebuild branch detection across all platform build templates. Backport verified by successful cherry-pick and conflict resolution. All changes are to build/packaging pipeline templates with no runtime code changes.
Risk
REQUIRED: Check exactly one box.
Changes only affect build and packaging pipeline templates. No runtime PowerShell code is modified. The enhancements add safety checks to prevent incorrect LTS package creation and improve diagnostics through better logging.
Merge Conflicts
Resolved conflict in .pipelines/templates/package-create-msix.yml where enhanced variable setting code with verbose logging was missing from release/v7.6 branch. Applied the complete enhancement from original PR.
