Round of USER-triggered deep-review fixes (11 CONFIRMED + 1 PLAUSIBLE, all
verified) on the 22-commit branch:
- collections: split the mutate-then-resync error surface. A resync READ that
fails after a successful Plex mutation no longer reports a false 422 "Plex
write failed" + rollback; it returns 502 "sync pending" (the next full sync
reconciles the mirror). New _write_or_pending_error helper; delete is exempt
(no Plex read). Covered by new happy-path / 422-rollback / 502 tests.
- New-collection dup-name guard is now advisory only: existingNames is the
search-scoped, all-library union, but the backend enforces uniqueness PER
library — so it no longer blocks a valid same-name collection in another
library, and the backend 409 is localized to nameTaken.
- member-remove now confirms before the write-through (matches delete-collection).
- add-title / new-collection library search render an error state on request
failure instead of a misleading "No matches".
- history: seed navCounter past the current entry's persisted sfScroll on load
so post-reload ids can't collide with back-stack entries and mis-restore scroll.
- PageScroller: LRU-cap the navId-keyed savedScroll map (was unbounded).
- share isIntrinsicReadOnly between the browse tile and the info page so the
lock/edit affordance can't drift.
