Make a Python Recipe Deployable

A deployable recipe is one that can be packaged into a container and run as a service. This skill writes the files that requires and configures the recipe to match.

It does not build an image, deploy anything, or provision infrastructure. Image builds happen later via Cloud Build → Artifact Registry; this skill's job ends when the files are correct.

The standard it implements lives in .github/policy.yml under deployability: — the minimum google-adk version, the required dependency list, the required file list, and the legacy app_utils file list. Change the standard there, not in the script.
