Native & Robust AppImage Management (Portable-by-click, Sandboxing, Snapshots, and libfuse fix)

Is your feature request related to a problem? Please describe.

Managing AppImages on Linux distributions often feels fragmented. While they provide great portability and isolation from system package managers, users frequently face several pain points:

1. Data Leakage & Portability Confusion: Standard AppImages or basic desktop integrators only redirect the executable or simple .home directories, often leaking user data into ~/.config or ~/.local/share (especially when XDG variables are exported by the session). Updating or renaming the AppImage file silently breaks these portable links (orphaned .home folders).
2. Dependency Issues: Older AppImages failing due to missing libfuse2 (especially on modern distros shipping libfuse3 / libfuse2t64).
3. Lack of Advanced Lifecycle Management: Users lack an out-of-the-box, unified way to handle updates, safe removals, sandboxing, and point-in-time snapshots of app data directly from the desktop environment.

Describe the solution you'd like

We propose integrating a robust, native AppImage management layer into Omarchy Linux (either by adopting core features from or deeply integrating existing stellar tools like Gear Lever and AM (AppMan)).

The ideal management layer should provide:

• Portable-by-Click: A seamless mechanism (or wrapper architecture) that guarantees application data, configurations, and XDG states are securely bound to a stable per-app directory (immune to filename changes or updates).
• Full Lifecycle Management: Intuitive options to Integrate, Update, Remove, and Snapshot app data directly from the system UI or CLI.
• Advanced Sandboxing: Built-in sandboxing capabilities (such as leveraging aisap or similar mechanisms popularized by AM) to enhance security for untrusted binaries.
• Native libfuse Independence / Fix: Out-of-the-box handling for libfuse2 compatibility (e.g., automatic fallback/extraction layers or runtime patching) so users never encounter the dreaded FUSE mounting errors on modern base systems.

Describe alternatives you've considered

• Relying entirely on manual wrapper scripts or third-party GUI tools post-installation. However, this fragments the user experience and leaves beginners struggling with orphaned data directories and broken paths.

Additional context & References

Integrating or drawing inspiration from these powerful open-source projects would make Omarchy Linux a powerhouse for AppImage workflows:

• Gear Lever: (https://github.com/mijorus/gearlever) - Excellent for desktop integration, updates, and managing app folders.
• AM (AppMan): (https://github.com/ivan-hc/AM) - Unmatched for package management, handling system-wide binaries, sandboxing, and robust portable configurations.

By bringing these capabilities natively into Omarchy Linux, users get the flexibility of universal binaries paired with the polish and stability of a curated operating system.
