- Line 111: Update the owner lookup around loadServedOwners so --dry remains
usable when the episode_book table is absent by treating only that specific
missing-table condition as an empty owner map; propagate all other database
errors unchanged. Preserve the existing owner-ID filtering and normal lookup
behavior when the schema exists.

- Line 114: Update the ownership handling around loadServedOwners and planShow
so a served ID belonging to the current show under a different catalog_key is
treated as a same-show key change, not as shared. Only populate eid_shared for
IDs owned by another show, while preserving episode recording and catch-up
behavior for the current show.

Summary
Episodes that a duplicate feed already holds no longer fail the book bootstrap or come back to it on every catch-up. They are stamped with the show that holds their ID.
Motivation
Podcast Index sometimes lists one podcast under two show IDs, and both lists share the same episode IDs. The book gives each served ID to one episode, so:
All 234 deferrals in a re-check of a 1,810-show sync run were this case.
What changed
lib/book-bootstrap.js:planShowtakes the current owners of the points' Podcast Index IDs. A point whose ID another key already serves gets no book row, so the show's transaction can't fail on it. If the owner is in the same show (a changed GUID under the same PI ID), the point is stamped with the owner'seidandcatalog_key; if it is another show (a duplicate feed), it goes intosharedand is stampedeid_sharedwith that show. The show's own episodes are still recorded in the same transaction.bootstrap-book.js: loads the owners before planning, countsshared, and the catch-up skips points stampedeid_shared.lib/episode-identity.js: a deferred episode is stamped with the owner's identity when the owner is in the same show, oreid_sharedwith the owning show otherwise, instead of nothing.Behavior & compatibility

Test plan
npm run test:sync --prefix scripts: 143 tests. 3 are new: a duplicate feed's point is left to the owning show and stampedeid_sharedwhile the rest of the show is recorded; a point whose ID another key of the same show serves is stamped with that key's identity and gets no row; and a deferred stage 4 episode is stamped with the owner's identity (same show) oreid_shared(other show).
