feat: warn when multiple frameworks detected (#643)

* feat: warn when multiple frameworks detected

When multiple build frameworks are detected for a target, emit a warning
listing all detected frameworks and which one will be used. Users can
override the selection with --compile-force-framework.

Fixes #414
