cli: Add support for dependencies in parent directories

Browse Source 
- Now supporting local dependencies in directories that are not contained in the docker context (ie. outside the folder containing langgraph.json)
- This is achieved by passing each parent directorty as an additional context to docker build
- This makes it a lot easier to build projects contained in monorepos where you need to include some sibling/parent folder as a dependency
- Also include additional comments in the generated dockerfile to delimit each section
