chore(AppMain): improve startup time 

- wrap everything we can in AppMain with a (async) Loader
- do not access globals w/o a proper store
- drop some dead code

Although I wasn't able to completely fix the bug, the ~50% improvement in
startup time is still worth trying imho. On my machine, the startup time
went down from ~7s to under 4s.
