Subject: [PATCH] Metadata, CI a dokumentace
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- metadata.txt: icon ukazoval na neexistující download.png – plugin se
  ve správci zásuvných modulů zobrazoval bez ikony; nastaveno na akce.png.
- Workflow: actions/checkout v2→v4 (v2 je deprecated, Node 12)
  a softprops/action-gh-release v1→v2.
- README: poznámka, že knihovna requests nemusí být na Linuxu součástí
  systémové instalace QGIS.

 The plugin is developed in **Python 3** using the **PyQt6** framework for the GUI and the **Requests** library for HTTP communication.
