📝 Drop stale theme-change listener from docs

The Islands editor-scheme mapping is now declared via the editorScheme
key in each theme JSON; the runtime listener no longer exists.

 ### Release workflow
 
 Releases are triggered by pushing any `v*` tag. CI (`build.yml`) builds the plugin, creates a GitHub Release with the zip artifact, then publishes to the JetBrains Marketplace using the `JETBRAINS_TOKEN` secret.
