Write a Compose UI desktop app akin to Chrome DevTools for Redwood/Treehouse

[JakeWharton]

We want to see the Compose node hierarchy and see recomposition counts and zipline services and Redwood protocol messages and all that fun shit!

Maybe a Flipper plugin(s)? Would be nice to reuse all that infrastructure provided it helps more than it hurts. Remains to be seen.

Recomposition counts come from here: https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/ui/ui-inspection/src/main/java/androidx/compose/ui/inspection/RecompositionHandler.kt;l=30;drc=31d53bd69c547c0665f04872a22feb525e5b875d

https://developer.android.com/reference/kotlin/androidx/compose/runtime/tooling/CompositionObserver is the new API coming for observability though.

Flipper looks like a bad choice, so probably just going to spin something custom with Compose UI for Desktop and websockets.

[JakeWharton]

Did a spike on this.

Blocked by:

• ktor accepting custom socket factories on client and server so we can use things like Android's LocalServerSocket.
• JetBrains Compose runtime 1.6 which has a new observability API. They'll take feedback on it. This should be where we get recompose and skip counts unlike Compose UI's current method-intercepting technique.

Android we do the unix domain socket web socket thing.

For iOS maybe https://developer.apple.com/forums/thread/658393
