Create a temporary Quarto project and write initial files into it. Returns an opaque projectId that is valid only while this server process runs.

Render the project, or one input file. Code execution is off unless execute is true. A Quarto failure is reported as success: false, with stdout and stderr preserved.

Return Quarto's inspect JSON for the project, or for one input file. The output is passed through without field changes.

Return the Quarto metadata that every new project receives as _metadata.yml, and the path of the file that holds it. An absent file returns empty metadata.

Store Quarto metadata, such as author, affiliation, and ORCID, for every new project. The call replaces the whole file. Send empty metadata to clear the defaults.
