v1.10.0: semantic search box in the panel

A magnifier in the panel header (next to the rebuild icon) opens a search box that
ranks the whole vault by meaning against a typed query (e.g. "goa characters",
"proofwork"), on the same mean-centered scale as the related-notes cards.

• store.rankByQuery(query): embeds the query, centers it with the corpus centroid,
  ranks entries by cosine to their centered means (floor = min(minSimilarity, 0.12),
  topK). Keyword fallback (query tokens vs note paths, excludes respected) when the
  engine can't embed or the index is empty, and on an embedding-dim mismatch.
• view: toggle search input; debounced; async results guarded against stale runs;
  render() yields to an active search; debouncers cancelled on close.

Verified by an adversarial review (verdict: ship).
