Replace /queues + /bookmarks + /captures with one /crabidy fs provider
whose track tomls link into a content-addressed store that de-duplicates
audio by provider id and by content hash (architecture/crabidy-store.md).
Green-field: no data migration.
- crabidy_store.rs: CrabidyStore owns the state tree (state_dir/crabidy)
and the data store (data_dir/crabidy); StoreIndex derived from the
.cbd-store.toml sidecars. save() enumerates a source into a temp folder
and swaps it in atomically (conflict refuses); capture_track dedups
(already-stored -> provider-id -> hash -> new). Queue persistence lives
here now (persist_current/load_current/save_snapshot/spawn_persister).
- capture.rs: reduced to enumerate + Downloader::download_to + Progress;
removed the Sink/capture_into/download-to-toml machinery.
- orchestrator: one crabidy_client + crabidy_store, single crabidy_owns
routing; get_lib_node annotates captured tracks via the store index.
- rpc: capture_error_status helper; save_queue link-saves the live queue
into /crabidy. playback persists/restores via CrabidyStore.
- tidal/youtube set Track.provider_item_id (track id / video id).
- cbd-tui: /crabidy/current, captured | row marker, delete confirmation
removed (deletes never touch the store), cache-invalidation + help text.
- delete bookmark_store/capture_store/queue_store; supersede their docs.
See plan/summary.md for deviations (SaveQueue RPC kept; fs id left empty;
shallow folder marking).
