"""
Worker Job Server — HTTP API that receives jobs from the Express API webhook receiver.

Instead of polling ERPNext for queued orders, this server receives webhook-triggered
job dispatches and executes them. ERPNext is the BPM orchestrator; we are the executor.

Endpoints:
  POST /jobs              — Receive a job dispatch
  GET  /health            — Health check
  GET  /jobs/active       — List currently running jobs

Jobs are executed in a background thread pool to avoid blocking the HTTP server.
Each job type maps to a handler function.

Architecture:
  ERPNext workflow transition
    → ERPNext webhook
    → Express API /api/v1/webhooks/formation/*
    → HTTP POST to this server /jobs
    → Handler executes (name search, filing, EIN, doc gen, delivery)
    → Handler calls ERPNext API to update status / advance workflow
