Scan a project directory and generate WORKFLOW.html — a visual system workflow showing all components, their communication paths, concurrency model, concurrent request capacity, and bottleneck analysis. Works with Python (FastAPI, Flask, Django), Node.js (Express, Nest.js), Go, and mixed projects. Detects: API frameworks, gateways, LLM providers, vector stores, databases, queues, rate limits, async primitives, and worker counts.

Scan a project and return the workflow analysis as structured JSON (no file written). Returns: framework, workers, capacity estimates, detected components (LLM, storage, queues, external sources), concurrency primitives (semaphores, rate limits), and bottleneck ranking.
