Crash on startup: Unhandled FSAL error when workspace contains an external `.asar` archive (`Cannot load file ... as it is a directory`)

Description

If an open workspace contains an extracted Electron application or archive (e.g., resources/app.asar), Zettlr crashes silently during startup with exit code 1 and cannot be opened again until config.json is manually edited to remove the workspace.

Reproducing

1. Open a directory containing an Electron .asar file (e.g., an extracted Electron app or package containing resources/app.asar) as a workspace.
2. Close Zettlr.
3. Attempt to launch Zettlr again.
4. The application exits immediately with code 1; no GUI window appears.
