Add --root-directory support to application:create and ship

[WendellAdriel]

Overview

The public API accepts root_directory when creating an application, but the CLI had no way to send it. Anyone with an app living in a repository subdirectory (a monorepo) could only create it from the dashboard or with raw curl.

Solution

Add a --root-directory option to application:create and ship, send it only when provided so existing requests stay unchanged, and expose rootDirectory in the JSON output. The shipped deploy skill now mentions the flag for monorepos.

Examples

cloud application:create --repository acme/monorepo --root-directory=backend --json -n
cloud ship --root-directory=backend -n
