- 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
- Add server support to `http-module`
- Ensure `DevelopmentService` works on all platforms (including posix)
- Ensure the built-in web server with dashboard works on all platforms (inluding posix). It still has some issues with certain featuers, but the basics work.
