Reorder: repo gains reorder(from, to) with remove-then-insert semantics
and contiguity preservation (5 tests); the local detail wires the existing
per-row chevron path (shown under Default sort - the repo order IS the
editable order; the Custom sort entry hides for locals since the custom-
order sidecar is u64-keyed) with optimistic model swap and off-thread
persistence.
Organization: additive favorite/hidden columns on local_playlists
(pragma-guarded migration + 2 tests incl. pre-migration shape), manager
cards render real heart/eye state and locals participate in the
visible/hidden toolbar filter, hidden locals drop from the sidebar while
staying reachable through the manager's hidden filter. Folder membership
for locals stays out of scope (folder tables are Qobuz-keyed).
main.rs wiring for these actions rides the next commit (shared file with
the in-flight favorites-rail batch).
