Remove Linux packaging and Qt dependencies section from README

Eliminated documentation related to Linux Qt dependencies and packaging tools, simplifying the README. This content is no longer relevant given recent architecture and tooling changes.

-## Linux packaging and Qt dependencies
-
-This library uses **Qt** on Linux. When you package your app for Linux, you must declare the required Qt runtime packages so the OS will install them if necessary.
-
-> **Heads-up:** In most cases, the only package that will be newly downloaded is **`libdbusmenu-qt5-2`** (≈300 KB).
-> Qt itself is widely used by many desktop applications and often comes preinstalled with the desktop environment, so users typically already have the necessary Qt runtime packages.
-
----
-
-### Developer setup on Ubuntu/Debian
-
-If you are developing or running locally on Ubuntu/Debian, ensure the runtime package is installed:
-
-```sh
-sudo apt-get install -y libdbusmenu-qt5-2
-```
-
----
-
-### Linking your app to Qt runtime packages
-
-If you use **jpackage** (Compose Multiplatform native distributions), you can use the dedicated Gradle plugin to declare the required dependencies automatically in the generated `.deb` control file:
-
-* Plugin: [GradleComposeDesktopLinuxDeps](https://github.com/kdroidFilter/GradleComposeDesktopLinuxDeps)
-* Apply it in your Gradle build (Kotlin DSL):
-
-```kotlin
-plugins {
-    // ... your existing plugins
-    id("io.github.kdroidfilter.compose.linux.packagedeps") version "0.2.2"
-}
-```
-
-Then configure it as follows:
-
-```kotlin
-linuxDebConfig {
-    addComposeNativeTrayDeps()
-}
-```
-
-For more information about distro compatibility and advanced options, please see the [plugin README](https://github.com/kdroidFilter/GradleComposeDesktopLinuxDeps).
-
-
-### Using Conveyor
-
-If you package with Conveyor, declare the dependencies in your `conveyor.conf`:
-
-```hocon
-app.linux.debian.control {
-  Depends: [
-    "libqt5core5t64 | libqt5core5a",
-    "libqt5gui5t64  | libqt5gui5",
-    "libqt5widgets5t64 | libqt5widgets5",
-    "libdbusmenu-qt5-2"
-  ]
-}
-```
