worker: wrap non-dict tool returns as {"result": ...} to match MCP shapes

The MCP server sets structuredContent = result if isinstance(result, dict) else
{"result": result} (zeromcp mcp.py:832), and domain.py parses that exact shape —
e.g. function_of() reads payload["result"] from lookup_funcs, which returns a
bare list. Our worker returned the raw list, so function_of got a non-dict and
returned None: hence "F5 — cursor is not inside a defined function" on Tab.

Replicate the rule in the worker's dispatch: dict passes through, anything else
(list/scalar) is wrapped as {"result": ...}. Fixes function_of and every other
list-returning tool (resolve_names, xref_query, list_funcs) in one shot.
