Critical fix. v0.4.0 and v0.4.1 crashed on first launch on any Mac that wasn't the build machine. SwiftPM's Bundle.module accessor for executable targets bakes in the dev machine's absolute build path, which doesn't exist on user machines — so onboarding traps an assertion before the first window appears.
Resource loading now goes through Bundle.main, which works correctly inside the shipped .app. Same UX as v0.4.1, just doesn't crash on someone else's Mac.
If you have v0.4.0 or v0.4.1 installed, replace it with this build.
