A Materials button on each AI task opens a picker: every node type of this
ComfyUI grouped by source (built-in, each custom node pack from
/object_info's python_module, page-only helpers, paid API nodes last), plus
combos, saved workflows, prompts and models by the names the AI's tools
use. Picks go to the AI as a user_toolbox step (message kind toolbox), in
begin_task and in full from get_toolbox; "only" makes add_node and
new_workflow refuse other custom or paid node types (built-in stay
allowed). Favourites stand in for tasks without picks. find_nodes lists
picks first and marks paid API nodes. open_workflow opens a saved
workflow in a new tab; a workflow's page can hand it to the AI.
Checked on the isolated ComfyUI with copies of the user's 10 node packs:
all 1642 node types can be placed, and a Comfyroll workflow ran.
