Adds support for passing user-defined fields to sub-agents by extending SubAgentTool’s JSON schema and attaching extra tool-call inputs as Msg.metadata, with corresponding docs and tests.

- Extend
SubAgentConfigto declare custom parameters (simple types or full JSON Schema) and required custom fields. - Update
SubAgentToolto include custom parameters in the generated schema and to forward non-built-in inputs into the sub-agent messagemetadata. - Add documentation (EN/ZH) and unit tests covering schema generation and metadata injection behavior.
