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

+How the function in 7-Zip returns object for output parameter via pointer
+
+1) The caller sets the value of variable before function call:
+  PROPVARIANT  :  vt = VT_EMPTY
+  BSTR         :  NULL
+  IUnknown* and derived interfaces  :  NULL
+  another scalar types  :  any non-initialized value is allowed
+
+2) The callee in current 7-Zip code now can free input object for output parameter:
+  PROPVARIANT   : the callee calls VariantClear(propvaiant_ptr) for input
+                  value stored in variable
+  another types : the callee ignores stored value.
+
+3) The callee writes new value to variable for output parameter and
+  returns execution to caller.
+
+4) The caller must free or release object returned by the callee:
+  PROPVARIANT   : VariantClear(&propvaiant)
+  BSTR          : SysFreeString(bstr)
+  IUnknown* and derived interfaces  :  if (ptr) ptr->Relase()
