Guided first-run setup (appctl setup).
The portable tool source is an OpenAPI document (file or URL): one contract, any stack.
Framework- and database-specific sync paths (Flask, Django, sync --db, …) are optional
heuristics for repos that do not have (or do not want to maintain) a spec; they are not a
substitute for a published OpenAPI contract when you need spec-accurate HTTP.
