fix: default prototype mode to deployment_target='none' (#855)

* fix: default prototype mode to deployment_target='none'

When --prototype is used without an explicit --deployment-target, default
to 'none' instead of picking the first available target. This avoids
pulling in unnecessary deployment-specific files for minimal projects.

* fix: correct Agent Engine console URL path

Add missing /agent-engines/ segment to the console URL so playground
and console links route correctly.

* refactor: combine deployment target auto-select conditions
