~x-ai/grok-latest → B (1:12)

Commit B is a substantive type-safety refactor: resolve_item now returns CanonicalItemUrl, call sites drop repeated CanonicalItemUrl(parse/clone) noise, pools/maps/HashSets use the newtype directly, and Deref is added on the URL wrappers—real lasting design cleanup across api/helpers, rpc, validate, and paths. Commit A only rewrites one button’s disabled attr as an @if/@else; a tiny local markup tweak with negligible ongoing impact.
