Summary

The dev mode strings "standalone" and "docker" are scattered as raw string literals across multiple packages:

• cmd/airflow.go (flag handling, mode resolution)
• airflow/standalone.go (mode field in PSStatus)
• airflow/docker.go (mode field in PSStatus)
• airflow/types/ps.go (referenced in comments)

A modeStandalone constant was added in cmd/airflow.go to fix a goconst lint warning, but ideally these should be shared constants in a central location like airflow/types so all packages reference the same values.

Suggested approach

• Define ModeDocker and ModeStandalone constants in airflow/types
• Replace all raw "standalone" / "docker" mode string literals across the codebase
• Keep flag name strings (e.g. "standalone" in PersistentFlags) as literals since those are UI concerns

Came out of review on #ai-84 (structured output support).
