The markdown renderer tracked list depth only to pick a marker. A
paragraph that follows a blank row inside an item started at column 0,
so a tool's catalog lines and its "Where it runs" paragraph read as
text after the list rather than part of the bullet. `rhema system show`
previews the prompt through this renderer, which is where it showed.
An item now records its content column, marker width included, and a
row the renderer starts inside one is padded to it. The paragraph that
introduces a sublist keeps it attached: the blank row the paragraph
asks for at its end is taken back, the hug a sublist already got when
no lead-in preceded it.
The tool sections put a blank row between the row and its description
so the description is a paragraph of the item — the shape the indent
applies to, where a soft break would have joined it to the schema.
