- 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
- External apps can opt into automatic cleanup when they exit, including tracked tasks, threads, files, directories, and memory.
- App-relative file paths resolve against the app’s working directory, with `.` and `..` normalized.
- The shell identifies ELF binaries that cannot be executed instead of treating them as scripts.
- Shared icon fonts now offer distinct default and large sizes, with updated icons across the interface.
- ESP32 apps can load additional ELF formats when address mirroring is enabled.
- Terminal colors render clearly on monochrome displays, and toolbar buttons have cleaner styling.
- GPS settings safely refresh their device list when their window is hidden or its widgets are destroyed.
