Bundle.module is a SwiftPM-generated computed property that calls
fatalError() when the resource bundle isn't found. This happens in
packaged .app bundles where SwiftPM's expected bundle paths differ
from the actual layout.
The fix uses manual bundle lookup (similar to ClawdbotKitResources.swift
and Textual's Bundle.textual) to search known locations without crashing.
This addresses the same class of issue fixed in Textual 0.3.1:
