seedance 0.2.1

//! Integration tests for the core framework contract.
//!
//! These verify the rules every agent-cli-framework CLI must obey:
//!   - exit codes match the documented contract (0, 2, 3)
//!   - `agent-info` lists every command that is actually routable
//!   - `--help` exits 0 even when piped
//!   - error envelope shape is { version, status, error: { code, message, suggestion } }
