LiHaohua a616511ed6 Add four czdev-runnable app demos ...

- apps/applaunch: prebuilt-emulator-app manifest that reuses the
  libAPPLaunch.dylib the emulator's own CMake produces from the
  UserDemo submodule. Zero edits to UserDemo.
- examples/lvgl_widgets: 3-line lv_demo_widgets() call, proving the
  force-loaded demo symbols from the emulator are reachable.
- examples/lvgl_music: lv_demo_music() — LVGL's built-in music UI.
- examples/key_echo: lv_demo_keypad_encoder() — keyboard-driven
  navigation demo covering the "pressing keys does something" case.

hello_cz gets a trivial text tweak.
