Nice, thanks for hopping on this so fast lol. If you wanna look into any other package size optimizations like this, that'd be great! I know you also mentioned locking down the esbuild versions?

Haha if this happens again, run pnpm i --fix-lockfile and it should resolve itself.

@Timeraa this good to go? Code looks good to me, and windows tests pass, so I think it's ready to go!
