optimizing perf of model loading

[jessfraz]

today this is not bad but there are things that can be improved, especially as we get into larger models:

Screen.Recording.2024-09-05.at.11.45.23.AM.mov

first we need to measure (some ideas):

1. time to app open
2. time to code load
3. time to syntax highlight
4. time to stream load
5. time to model load

I like how vscode priotizes time to code load, then does syntax highlighting etc, more info here: https://www.electronjs.org/docs/latest/tutorial/performance

I bet we can make stream load faster too, cc @paultag @iterion

anyways considering thus far we have put zero effort into this i am sure it can be fast as fuck with actual effort

I'll be opening a PR for this feature.

Here is one of the sample outputs when I run ./out/Zoo\ Modeling\ App-linux-x64/zoo-modeling-app ~/Documents/zoo-modeling-app-projects/default/cube.kcl from a locally packaged binary from yarn tron:package

• time to app open -> didLoadFile because we are loading the /file route.
• time to code load -> startExecuteAst because this is when the code can actually run
• time to syntax highlight -> willSyntaxHighlight and didSyntaxHighlight
• time to stream load -> startInitialEngineConnect and endInitialEngineConnect
• time to model load -> endExecuteAst

I added a few other marks in the application to help understand time to app open.

It took 8 seconds for my auth :(
