rfc: installing the app gives real-time openspec-flow notifications

When the app is installed, the app should be able to show the required notifications, so that we can see the eyes, we can see the comments, and we can have a more real-world experience, with the work still being done in the actions

The issue names the installed app and the existing actions flow, but no files or tests. Start by reviewing how installation currently works and how actions handle the work; done means the installed app presents real-time notifications for eyes and comments while that work continues in actions.
