mkit

Drive the `mkit` CLI — a content-addressed version control tool with BLAKE3 object IDs, Ed25519-signed commits, and native in-toto/DSSE attestation. Use this when working in a `.mkit/` repository, making signed commits, managing signing keys, producing or verifying supply-chain attestations, inspecting content-addressed objects, or syncing over `mkit+ssh`/`https`/`s3`/`file` transports. mkit mirrors git's CLI/UX, so git muscle memory applies — this skill focuses on the parts that are *not* like git.
