Search indexed release notes. Defaults to hybrid retrieval (FTS5 + semantic vectors fused via RRF). Results carry a `kind` discriminator so agents can branch on `release` vs `changelog_chunk` hits. When Vectorize or the embedding provider is unavailable, the tool silently degrades to lexical FTS and flags the result.
