fix: note list shows incomplete relationships when opening from sidebar

Two root causes:
1. noteListHooks used a stale selection.entry to build relationship groups —
   now looks up the fresh entry from the entries array so relationship updates
   propagate immediately.
2. frontmatterToEntryPatch didn't update entry.relationships — added
   RelationshipPatch support so frontmatter changes also update the
   relationships map in state.
