Replace directory-scoped image APIs with flat PostgreSQL-backed storage and stable meme_id resource contracts. Remove directory endpoints, sidecar assumptions, and path-based media access while preserving task, upload, rename, delete, repair, and search workflows. Archive the image ingestion and library OpenSpec change with migration and contract coverage.
