recall@1 60% to 72%, answered 48% to 72%, latency 3x better. But false
recall went 1/5 to 5/5: e5 packs every score into a narrow high band, so
the 0.55 gate now admits everything. Left the gate alone as instructed.

Real recall is 48% after the gate, and one must-be-silent query gets an
answer anyway. Review finding 2 (the score distributions overlap, so no
gate separates a real recall from a false one) and finding 4 (the memStore
branch at voice.go:776 is unreachable for notes). Adds an embedder cache
so the gate sweep does not re-embed the fixture nine times.
