Add §8.0 TrackEntity → Release/Track normalization as a breaking
pre-requisite before Phase 8 UI. Fold in review decisions: Waveform tab
removed (in-grid status column + per-row/page-level generate),
ViewModel is DI-scoped (TracksViewModel pattern), BatchEdit confirmed as
a new page sharing extracted sub-components. Dissolve the AlbumSummaryDto
widening question (Release table supplies the fields directly).
