- Add gui_emu_tools: emuMMC Manage window with correct positioning (LV_PROTECT_PARENT + re-parent to win) - Tools: single SD button (tap = SD partition manager, 3s hold = eMMC) - Remove emuSD from Nyx UI (tabs, UMS, partition manager); keep bootloader emusd - Shorten Create emuMMC description text by one character - Storage/build/config and dependency updates Co-authored-by: Cursor <cursoragent@cursor.com>
