v1.1.0

EntraGroupMirror is now a PowerShell module on the PowerShell Gallery.

Install-Module EntraGroupMirror -Scope CurrentUser

New

• -Diff mode — Copy-EntraUserGroups -Diff (or Compare-EntraUserGroups) shows a read-only side-by-side comparison of two users'' memberships: source-only, target-only, shared — with notes on groups that cannot simply be copied.
• Pester test suite — 16 tests with fully mocked Graph responses, running in CI next to PSScriptAnalyzer.
• Automated publishing — GitHub releases publish the module to the PSGallery.

Changed

• Restructured as module EntraGroupMirror with exported cmdlets Copy-EntraUserGroups and Compare-EntraUserGroups; the standalone root script moved into the module.
• Console output is now English.
