Subject: [PATCH] fix(cli): derive default API debug port from configured API
 port
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previously `defaultApiDebugPort` was hardcoded to 18911, causing port
conflicts when running multiple Redwood apps simultaneously. Now it
is derived from the configured API port (e.g. api.port=8912 → debug
port 18912), matching the pattern used by `apiPreferredPort`.

Fixes #10937
