Added before/after tab drop handling with an insertion marker, and regression coverage for tab ordering and selection preservation.

Defers session bookmarks, dirty-draft snapshots, and dirty-file conflict checks until after the selected editor is visible; adjacent no-op drops no longer invalidate tab state.

Ensures updater, settings, help, and support commands dismiss conflicting transient sheets before presenting.
