Create function

Create a new Zavu Function. The function starts in draft status. A dedicated API key is auto-provisioned and injected as the ZAVU_API_KEY secret so the function can call back into the Zavu API without manual setup.

Provide sourceCode to seed the draft. Call POST /v1/functions/{functionId}/deploy afterwards to publish.
