Add own-work tracking, Claude hand-off check, and weekly recall

- Long pastes into Observe/Interpret/Apply are tagged as pasted; notes show
  Mine / N pasted and an own-words share. Pastes follow text through merges.
- The "-> Claude" buttons on the Script stage ask first when a chunk lacks
  enough of the user's own (non-pasted) words.
- Weekly recall card on Home: write a passage from memory, compare with notes,
  self-rate; recalls are saved on the chunk and synced.
- Recall history on Home with an eight-week strip and the full list.
