agent-platform 0.2.0

Private developer-surface release. Adds one shared executable API route catalog, deterministic OpenAPI 3.1 at /openapi.json and through the CLI, and a responsive Rust-built documentation site embedded in the binary at /docs/. The OpenAPI digest is 7aab7b4ee044bc8709c63aaee3a3c64a3a6aee11b97a4dd06bd20b7b37585d3a. Durable persistence, production Identity, live Connector invocation, workers, and trigger delivery remain future waves.
