It seems either nobody knows or nobody cares.

Hello, did you manage to solve this issue somehow? There is so little data about this issue in the internet.

I have initially created a standalone watch application. What are the options do I have if I want to make it dependent on iOS now? Is the only option to make it happen - to completly rebuild the app with a new name?

This is happening to me to. Seriosly Apple please fix this I can not get my system updates because of that. And please do not suggest me do turn-off-turn-ons and safe mode. I did it all already. Just fix your problem and everyone will be happy.
