feat: use zod to parse the yaml

[saihaj]

• swap all the manifest usages to remove immutable
• generate a JSON Schema
• Test out YAML file autocomplete VsCode with JSON Schema
• refactor manifest validation logic to not use immutable
• add tests for manifest parsing

I am testing out with some example subgraphs and there are still things that break for this one
