docs: the nine-op surface shipped, and two of its primitives are the wrong shape

lang/AGENTS.md said the collapse was 'not yet compiled into the MCP server'.
Verified against the live tool surface: it is exactly the nine ops. Noted that
think's faculty parameter and ground's minted edge are both documented as the
wrong shape.
