LLeMbas's own window, the leaf icon, one name for the app

- The window has no system decoration: a local title bar webview (agent
  state, a native menu with the tray's items, window buttons) above the
  content webview, which stays remote with no IPC. Laid out on resize,
  with a frame to resize by unless maximized.
- Icons from the transparent pixel leaf, not the server's tiled icon.
- productName llembas-desktop: package, .desktop file and the window's
  app id now match (KWin showed a generic icon); the visible name stays
  LLeMbas through a desktop template. Replaces the 0.1.0 package l-le-mbas.
- The bundled CLI is a resource in the app's own directory, not
  /usr/bin/lembas.

 ## [Unreleased]
 
+### Added
+
+- The window is LLeMbas's own: a title bar in the LLeMbas look with the server's address, the
+  agent's state, a menu (the tray's items, plus Reload) and the window buttons. Closing still keeps
+  the app in the tray. The server's pages stay in a view of their own, with no access to the app.
+
+### Fixed
+
+- The app icon is the leaf alone, on a transparent background, instead of a dark square tile.
+- The window shows the app's icon instead of a generic one (the window, the menu entry and the
+  package now share one name, `llembas-desktop`).
+- The package is called `llembas-desktop` (it was `l-le-mbas`) and replaces the old one.
+- The bundled LLeMbas CLI is installed in the app's own directory instead of as `/usr/bin/lembas`,
+  where it could hide, or be hidden by, a `lembas` installed by hand.
+- `SHA256SUMS` on the GitHub release no longer lists itself.

 ## [0.1.0] — 2026-10-14
