Put llm and kai_decide on the default hanzo-mcp surface

Every mode disables a registered tool it does not list, and llm was
listed nowhere but HEAVY_TOOLS, written when it pulled a 100 MB client.
It is an HTTP call to api.hanzo.ai now, so llm and kai_decide join the
essential set every personality carries, and the llm package maps to the
two tools it ships.

hanzo-mcp 0.15.19, on hanzo-tools 0.3.8 and hanzo-tools-llm 0.2.1.
