oasb-scaffold

OASBuilder pipeline package conventions for scaffolding new stages. Use when creating a new oasb-* package, scaffolding an OASBuilder stage, setting up a hatchling Python pipeline package, or following OASBuilder conventions for CLI, schema, validation, and LLM call patterns. Also use when adding a new stage to the oasb-complete workspace, working in any oasb-* repo, or when the user mentions "OASBuilder conventions", "pipeline package", "oasb-scaffold", or asks about the standard pattern for oasb packages.
