Create a branch

POST/v1/projects/{projectId}/branchesCreate a branch

⚠️ Experimental endpoint: this API is in active development and may change at any time without notice. ⚠️

Creates a Branch under the specified Project. The first Branch in a Project is always created with isDefault=true and role=production regardless of the body value. Later Branches are created with role=preview. Setting isDefault=true while another Branch already holds the default atomically swaps the default flag only.
