Linux artifact broken

Description
Currently the Linux artifact build by CI is broken and can't be run after download.

Environment
Production

Application (+ app version, build, operating system)
MM Version: 2026.1.1
OS: Fedora 43 (but any Linux)

Steps to reproduce

1. Download linux artifact
2. Run the executable

Actual results
The app silently crashes if run from DE and throws error if run from console.

Expected results
The app will launch

Notes
The executable is looking for lib/ directory, but only lib64/ is available. After fixing this, the platform libs load system libraries, but they should load the packed ones instead. That can be temporarily fixed by LD_LIBRARY_PATH=./lib:$LD_LIBRARY_PATH ./bin/MerginMaps. Fixing this will launch the app, but it crashes on
QtQuick libs.

FATAL ERROR: unable to create main.qml

Start by running the downloaded Linux artifact from a console and inspect the paths used by bin/MerginMaps, especially the missing lib/ versus available lib64/ directories. Check how the platform libraries and QtQuick dependencies are packaged and resolved, including qrc:/com.merginmaps/imports/MMInput/main.qml. Done means the downloaded executable launches with its bundled libraries and loads QtQuick.Controls without the reported errors.
