📄 Description

Description

Fixes runtime context docs to use the correct API patterns: @dataclass (Python) / Zod schema (TypeScript) for context_schema, context=Context(...) keyword arg for passing context at invoke time, and ToolRuntime for accessing context in tools. The previous examples incorrectly used plain dicts for context_schema, config={"context": {...}} for passing, and config.get("context") for access — which was a common source of confusion.

Resolves DOC-951
