- Added POSIX desktop support for SDK builds, application packaging, and integration testing. - Added POSIX filesystem partitions and improved application path handling. - Added simulator support for loading and running applications dynamically. - Improved simulator task stack handling and display startup reliability. - Improved simulator display scaling, resizing, high-DPI support, and pointer accuracy. - Fixed LVGL timers and input polling on POSIX. (fixes simulator with Linux on some Intel graphics platforms) - Standardized data paths across platforms. - Logging now works via separate task: this allows apps to write to log without it affecting their stdout (for apps that output text as relevant date for other apps, like the File Selection app) - Fixes for app stdio
