Wave 9 (K-manual): add a book by hand, no ISBN required

Committed by tasks/wave-chain.sh after its mechanical gate passed
(assembleDebug, testDebugUnitTest = 241 tests, verifyPaparazziDebug, no build
files touched, no "always 'false'"). ORCHESTRATOR REVIEW STILL PENDING.
Prompt: tasks/K-manual.txt. Worker: $5.051114400000003, 108 turns.

+- `app/app/src/main/java/org/modg/bookshelf/ui/add/AddBookViewModel.kt`: added a KDoc comment on `uiState` explaining the `WhileSubscribed` caveat for future readers — no behavioral change.
+- Recorded and eyeballed the new Paparazzi goldens (`AddBookScreenPaparazziTest` ×3 states ×2 themes, `LibraryScreenPaparazziTest` re-recorded ×2 states ×2 themes) — all render correctly: form fields, ISBN error state, duplicate warning, the new satellite "Add by hand" FAB, and the empty-state secondary button, in both themes.
+
+Nothing else touched — the feature itself (screens, nav, routes, entry points) is exactly as the previous worker left it.
