v0.1.0

v0.1.0 — first release

Hard-delete and verify erasure of a data subject from a pgvector store: forces the
physical reclaim (REINDEX + VACUUM) a plain .delete() skips, then reports removal with
Postgres's own residue signal. Honest boundaries baked into the report; self-hosted-first.
pgvector only in v0.1. See the README.
