morris 150466f598 refactor(lcd): use LZ4-compressed binary images in i80_controller example 
- Remove the EXAMPLE_LCD_IMAGE_SOURCE Kconfig option (embedded binary vs
  file system) and always load images from LittleFS.
- Convert the PNG images into LZ4-compressed LVGL binary images (.bin)
at
  build time using LVGLImage.py, and flash them to a LittleFS partition.
- Upgrade lvgl to 9.6.0 and add the espressif/lz4 component; link the
external LZ4 library into lvgl.
- Split the example: main.c focuses on the esp_lcd i80 API, while the
LVGL
  porting (lvgl_port.c) and the UI (lvgl_demo_ui.c) live in separate
files.
- Rework the demo animation to use the LVGL animation engine (lv_anim)
with
  easing paths instead of a manual software timer for smoother
rendering.
- Remove the embedded C image arrays (esp_logo.c, esp_text.c) and the
  obsolete sdkconfig.ci.image_in_{bin,fs} variants.

Chen ChenandCursor b63ecdc5a0 fix(i2s): use GPIO5 as wav_player default DOUT 
GPIO7 is an MSPI flash pin on ESP32-H4, so the example fails to init I2S on that target.

richardsonnick acebd79894 fix(examples): use 'n' instead of '0'/'false' for bool Kconfig defaults 
'0' and 'false' are not valid values for a bool symbol. The parser emits
a note and falls back to 'n', so the resulting configuration is correct
but the build is noisy. Set the two remaining example symbols to
'default n' to make the value explicit and silence the note.
