This pull request updates the dashboard and the public API components to use the new workspace model, which has nested fields for spec, metadata, and source. It also adds new RPCs and methods for updating and parsing the workspace metadata and spec, and simplifies the environment variable API. It modifies several TypeScript, Go, and proto files, and adjusts the cache version and the end-of-file-fixer command.
