[Bug] App says it is incompatible with macOS on Apple Silicon (M4) / macOS 15.7.4

## Summary
Flow Finder launches, but macOS immediately shows a compatibility warning saying:

> “This version of the application ‘FlowFinder’ cannot be used with this version of macOS.”

## Environment
- Device: MacBook Air 13-inch
- Chip: Apple M4
- macOS: 15.7.4
- App version: 1.38.0
- Install source: GitHub Releases DMG

## Steps to reproduce
1. Download Flow Finder from GitHub Releases
2. Open the DMG
3. Drag FlowFinder to Applications
4. Launch FlowFinder from Applications

## Actual result
The app window appears, but macOS then shows a dialog saying this version of FlowFinder cannot be used with this version of macOS.

## Expected result
The app should run normally on Apple Silicon Macs that meet the stated minimum macOS requirement.

## Notes
- My machine is Apple Silicon (M4)
- My macOS version is 15.7.4
