docs: sync CLAUDE.md files with current architecture

Drop the removed tag system, fix the retired Manual status and the atomic
queue-claim location, refresh the App DI registrations to the Islands VMs,
update the Data table list, correct a stale test reference, and document the
interface-folder and single-consumer-fold conventions plus the .NET 8 build path.

-- **Transients**: TaskEditorViewModel, ListEditorViewModel (created per dialog)

+- **Transients**: modal VMs (`SettingsModalViewModel`, `MergeModalViewModel`, `ListSettingsModalViewModel`, `RepoImportModalViewModel`, `WorktreeModalViewModel`, `WorktreesOverviewModalViewModel`, `PrimeClaudeTabViewModel`), several exposed as `Func<T>` factories for on-demand dialog creation
