Add .qmlformat.ini, qmlls support, and format QML files

- Enable QT_QML_GENERATE_QMLLS_INI for QML Language Server support
- Add IMPORT_PATH to demo's qt_add_qml_module so .qmlls.ini includes
  the local build QML directory alongside the Qt system path
- Add editor setup section to README with qmlls and qmlformat guidance
- Add QML formatting section to French guide
- Reformat demo QML files with .qmlformat.ini (line wrapping at 80 cols)

+## Editor setup (QML Language Server)
+
+The build generates `.qmlls.ini` files so that qmlls can resolve both Qt and local Bobink QML imports.
+
+**Neovim** — works out of the box if your LSP config picks up qmlls.
+
+**Qt Creator** — enable the language server under Edit > Preferences > Language Client > QML Language Server.
+
+**QML formatting** — a `.qmlformat.ini` is included at the project root. `qmlformat` picks it up automatically from the terminal (`qmlformat -i file.qml`). Qt Creator does not respect `.qmlformat.ini` or its own Code Style settings when formatting ([QTCREATORBUG-29668](https://bugreports.qt.io/browse/QTCREATORBUG-29668)) — use the command line instead.
+
+**Submodule users** — since `QT_QML_GENERATE_QMLLS_INI` and the demo are only enabled for top-level builds, add these to your own project:
+
+```cmake
+# Enable .qmlls.ini generation
+set(QT_QML_GENERATE_QMLLS_INI ON CACHE BOOL "")
+
+# Add the build QML directory so qmlls can resolve the Bobink import
+qt_add_qml_module(YourApp
+  URI YourApp
+  ...
+  IMPORT_PATH "${CMAKE_BINARY_DIR}/qml")
+```
+
