Problem

generate_mind_map() does not accept language or instructions parameters, unlike every other artifact generation method (audio, video, report, slides, infographic, etc.). The payload has hardcoded static values:

["interactive_mindmap", [["[CONTEXT]", ""]], ""]

This means mind maps are always generated in English with no custom instructions.

Expected behavior

generate_mind_map() should accept language and instructions parameters, consistent with other generation methods, and pass them into the RPC payload.

Fix

Based on the RPC payload structure, language goes at params[5][2] and instructions at params[5][1][0][1]:

 async def generate_mind_map(
     self,
     notebook_id: str,
     source_ids: list[str] | None = None,
+    language: str = "en",
+    instructions: str | None = None,
 ) -> dict[str, Any]:

-["interactive_mindmap", [["[CONTEXT]", ""]], ""]
+["interactive_mindmap", [["[CONTEXT]", instructions or ""]], language]

The CLI generate command should also expose --language and --instructions flags for mind maps.
