Generate specs from the codebase

For: Adopter

First scan: an adopter runs usm scan after init and gets .usm files for every detected service, route, and data source.

Part of: Scan Command

Steps

• Run (cli) — usm scan in the repo root after init created usmconfig.json
• Review (cli) — console output — services, routes, and data sources matched against expectations
• Inspect (spec) — generated .usm files in .usm/ for gaps or wrong detections

How this is verified

• .usm/services/*.usm files created for each matched app
• .usm/features/*.usm files created from route extraction
