- The `/system` FAT volume is removed. Its files are embedded in the firmware as generated C arrays. - Default-size fonts are generated at build time and used from flash. - The LVGL task and the Launcher run on PSRAM-preferred stacks. A new kernel `file_ops` API takes the file work off those threads. - `MainDispatcher` is reimplemented as an on-demand task. - More long-lived state is allocated with the PSRAM-preferring helpers. - Other fixes and improvements
