Generate a BRD from an ERPNext Lead
Adds the Lead-to-BRD flow: search live CRM Leads over the ERPNext MCP gateway, fill a scoped form (product, modules, detail level, requirements, delivery), save drafts per author, and generate at low/moderate/high depth or as a quick half-depth draft. Slugs the generated document's client from the Lead id and routes /leads, /lead-drafts and /lead-to-brd.
