patriandClaude Opus 5.5 9684ab39f2 display_gif_embedded: port to LVGL 9.6.0 (20.6 -> 23.4 fps) 
- lvgl/lvgl@9.6.0 via lib_deps, lv_conf.h from the 9.6 template
- scr_st77916.h: lv_display/lv_indev API, RGB565 byte swap in flush,
  lv_tick_set_cb
- FPS counter via display refresh events
- loligod.c: lv_image_dsc_t descriptor

GIF now plays at its own frame rate; decode time halved by LVGL 9.6's
AnimatedGIF decoder.
