hybrids3v0.3.8

Self-hosted lightweight object storage speaking three interfaces at once — the S3 API (boto3 / AWS-SDK compatible, AWS Sig V4), a plain HTTP API (curl-friendly, Bearer auth), and MCP (Streamable HTTP tools for agents). Buckets/objects with SQLite metadata and flat-file storage on disk; buckets are config-defined (no create/delete API), each with a public/private flag, a private key + public key pair, optional TTL expiry, and a max upload size. Auth is per-bucket keys plus a cross-bucket master key; presigned GET/PUT URLs for handing out single-object access. Use when the user wants to put/get/list/delete files in a self-hosted S3-compatible store, generate presigned upload/download links, drive their own boto3-compatible object storage, or connect an agent to object storage over MCP.
