- Add dynamic incrementalist.baseBranch variable to pipeline templates - Use System.PullRequest.TargetBranch for PR builds - Default to 'dev' for non-PR builds - Update all Incrementalist commands to use --branch parameter This allows PRs targeting version branches (e.g., v1.5) to correctly compare against their target branch instead of always using dev, avoiding unnecessary full builds.

- Use PowerShell script to extract branch name from System.PullRequest.TargetBranch - Strip 'refs/heads/' prefix from target branch reference - Set IncrementalistBaseBranch variable dynamically at runtime - Update all Incrementalist commands to use the new variable This fixes the issue where PR builds always used 'dev' as the base branch even when targeting version branches like v1.5.

Summary
Changes
incrementalist.baseBranchvariable to pipeline templates that:System.PullRequest.TargetBranchfor PR builds--branch $(incrementalist.baseBranch)parameterImpact
When a PR targets v1.5, Incrementalist will now correctly compare against v1.5 instead of dev, avoiding full builds when only specific projects have changed between v1.5 and the PR branch.
This solves the issue where PRs to version branches would always trigger full builds because Incrementalist was comparing against dev (which contains v1.6 code) instead of the actual target branch.
Test Plan
The pipeline changes will be validated when this PR runs through Azure DevOps.
