v0.1.0 - agent.3md standard kit
First release of the agent.3md standard: one 3md file is a whole agent (identity + on-demand skills). Includes the spec, the TS reference loader (@corvidlabs/agent3md), Rust + Swift loaders, a validator + conformance vectors, a CLI, an MCP server, JSON projection, and the token-savings/flat-scaling proofs.
