Fans the frozen ETag/If-Match/412 recipe (Block reference, #253) onto the Playlist aggregate: - ReplacePlaylistItems command carries ExpectedVersion; the handler runs CheckVersion as a standalone Either after validation (so a stale write survives as 412, not flattened to 422 by Apply/Join), bumps Version unconditionally before saving, and persists via SaveChangesWithConcurrencyGuard (EF concurrency-token backstop). - PlaylistViewModel carries Version; the items GET sets a strong ETag and the PUT parses If-Match, threads it into the command, and returns the refreshed ETag on success (400 on a malformed If-Match). - Sibling item-adding handlers (AddItemsToPlaylist, AddMovie/Episode/ Season/ShowToPlaylist) bump Version too, since they mutate the same editor-visible item list. - SPA: playlists.ts exposes getPlaylistItemsWithMeta and an If-Match-aware updatePlaylist; PlaylistEditor holds the ETag in a ref, round-trips it on save, and opens a "changed elsewhere" ConfirmDialog on 412 (mirrors BlockEditor). Tests: new ReplacePlaylistItemsHandlerConcurrencyTests (stale/match/ force-write/no-op-bump/racing-save), new PlaylistController tests (ETag on GET items, 400/412/thread-version/force-write on PUT), and a vitest 412-conflict-dialog test for PlaylistsScreen. dotnet test: 1304/1304 green. web: npm run typecheck clean, npm run build clean, vitest 664/664 green. Ref #253 PR2.
