LangGraph Deployment Asset Generator

Create a small utility that turns a validated LangGraph configuration into ready-to-use deployment assets. The utility should delegate Dockerfile and compose scaffolding to the dependency's generation features instead of hand-written templates.

Capabilities

Dockerfile creation

• Given an output path and config file, generate a Dockerfile that reflects the config defaults; error cleanly when the config is missing. @test
• When a base image override is provided, the generated Dockerfile uses that image tag instead of the config default. @test

Compose scaffolding

• When compose scaffolding is enabled, create a docker-compose.yml in the output directory that references the built image tag and exposes the configured API port. @test
• Compose scaffolding also writes matching .env and .dockerignore files based on the config (or a provided env file), ensuring the generated files sit beside the Dockerfile. @test
