app-module - Apps now have support for: - environment variables (inherit from parent app) - current workdir - window size (when running in terminal) - Add type aliases like `AppId` and `PackageId` - Remove data duplication between ledger and app instance records: create `AppManifestSet` - `AppManifest` usage safety improved: pass by value where needed, or use `AppId` instead of a manifest. Terminal and shell - Moved shell commands into coreutils-module as proper apps. - Refine stack size for terminal and shell because apps now run with their own task and stack (including in-memory apps) Platform - Fix for listing root dir on ESP32: wrap posix directory functions and wire in file systems. - Moved all platform-specific file system init code to platform subprojects Other - Fix for screenshot capture (issue with paths) - Fixes for coreutils app correctness - Memory optimizations (use more PSRAM where possible) in various locations such as app-module, shell and terminal. - `ls` and `help` commands now use terminal width and show columns of data by default - Created fs helpers at `TactilityKernel/include/tactility/filesystem/fs.h` (partially ported from `ShellFs`)
