Fluorine Manager: full Linux port of Mod Organizer 2

Complete native Linux port with FUSE-based virtual filesystem,
Proton/umu-run integration, and Flatpak packaging.

Key features:
- FUSE VFS replacing Windows USVFS (in-process + standalone helper for Flatpak)
- Proton/GE-Proton/umu-run launcher with env var forwarding
- Flatpak support (sandbox-aware VFS, NXM handler, umu-run)
- Wine prefix management UI
- Case-insensitive path resolution for Linux filesystems
- QSettings-safe INI handling (avoids Bethesda INI corruption)
- Portable instance support with auto-generated launcher scripts
