🔧 Add PackageReleaseNotes merge conflict resolution utility

Added Resolve-PackageReleaseNotesConflicts.ps1 to automate resolution of merge conflicts in all PackageReleaseNotes.txt files by keeping both sides (current branch first, then incoming) and staging the resolved files. Simplifies future merge workflows.

🩹 fix: scope net11 method-count expectation to linux

The NET11_0_OR_GREATER guard previously adjusted the expected method count

the adjustment in an OperatingSystem.IsLinux() check ensures the correct
expected count is applied on Linux while leaving other platforms unaffected.
