build-stack-v2

EXPERIMENTAL deterministic builder for a whole n8n workflow STACK (multiple sub-workflows wired via Execute Workflow), JS-orchestrated. Takes a PRP-style end-to-end use case, decomposes it into sub-workflows along known rules, fixes the handover contracts between them, documents the architecture (mermaid) in one central file, then builds each sub-workflow bottom-up via build-workflow-v2. Two modes: GREENFIELD (new stack) and EXTEND (change an existing one). Decomposition rules, build order (topological), and per-sub-WF gates are JS control flow the model cannot skip. Use for multi-workflow use cases; for a single workflow use build-workflow-v2.
