fix(mcp): drop hardcoded section list from get_design_prompt description

Browse source 
The tool-level description still listed 11 specific sections (schema /
layout / roles / text / style / icons / examples / guidelines /
planning / elements / design-md) even though the actual catalog has
28. Replace with a pointer at inputSchema.section.enum, which is
already derived from listPromptSections() — the description now
can't go stale as sections are added or removed.

D0 parity snapshot refreshed for the new description text.
