Three layering cleanups from REVIEW.md §5 / §3:
- Drop the three private `is_unique_violation` helpers in
repo::{user,chapter,bookmark} in favour of sqlx 0.8's
`DatabaseError::is_unique_violation()` method (already used by
repo::collection).
- Remove the unreachable 23505 branch in repo::chapter::create — the
(manga_id, number) UNIQUE was dropped in 0013, so the defensive arm
could no longer fire. A doc note records what to do if uniqueness
is re-added.
- Move three inline SQL queries out of handlers/daemon into repo
functions: bookmarks' chapter-belongs-to-manga guard
(`repo::chapter::belongs_to_manga`), the daemon's dispatch lookup
(`repo::chapter::dispatch_target`), and the daemon's page_count
safety net (`repo::chapter::page_count`). Restores the
handlers→repo layering invariant in CLAUDE.md.
- New `crawler::url_utils` module consolidates host_of / origin_of /
registrable_domain — they used to live in three crawler submodules
with diverging edge-case behaviour. Tests moved with them.
- Doc cross-references on repo::author::set_for_manga and
repo::genre::set_for_manga pointing to the crawler's name-keyed
variants, so the intentional duplication is discoverable.
