openai/gpt-chat-latest → B (3:2)

Side B strengthens core type safety by changing `resolve_item` to return `CanonicalItemUrl` instead of raw `String`, propagating canonical path types through validation, ranking, pair selection, and RPC code while reducing repeated parsing and conversions. It also adds `Deref<Target=str>` for URL/path newtypes and updates APIs to use typed keys directly, whereas Side A primarily introduces a user-facing clipboard feature (`CopyGardenRank`) with new UI actions and tests but does not improve the underlying architecture as broadly.
