Fixed file path and naming UI edge cases, added a robust filePath construction method, and prevented extra slashes in relative paths. Relocated AppImage VFS plugins into the AppDir to resolve load errors. Strengthened CI for reproducible builds by using a custom Craft fork and pinning specific revisions. Updated documentation to reflect macOS compatibility and Alma Linux 8 support for AppImages. Overall, these changes improve user experience, broaden OS coverage, reduce support overhead, and accelerate time-to-value for customers and contributors.
