app-module:
- Implement `AppStartContext` to reduce amount of `app_start_` and `app_exec` functions: replace them with `app_start_with_context()`
- Add support for environment variables when starting apps
- Implement support for environment variables for apps
graphics-module:
- Add this new module
- Move font-module code into this module
- Implement pixel_buffer
apps:
- Terminal app: reduce memory usage by only buffering a single row of characters, and try to buffer in IRAM when possible. Implement new pixel_buffer.
- App List: Mark apps as favourite to pin them on top. Use touch or press "x" key.
- App List: Add toolbar button that shows alert dialog with info about using favourites
Features:
- Implemented terminal app based on BreezyBox
- Implemented shell based on BreezyBox
- Added font-module with fixed-width fonts
Improvements:
- Improved application standard-output and error-output routing, including dynamically loaded applications.
- Updated shared icons and Material Symbols mappings.
- Other improvements & fixes
- Apps can be launched directly from file paths (including Files app support)
- Added executable detection to identify unsupported or invalid binaries before launch.
- App startup is now streamlined through separate registered-app and direct-execution interfaces.
- Existing app launch points were migrated to the updated startup APIs.
Implement file IO for applications to facilitate text input/output capturing.
Apps can now launch apps and:
- Read their stdio output
- Write to their stdio input
- Apps can specify task stack depth and preferred memory placement in their manifests.
- App identifiers are validated against length and character requirements.
- Crash diagnostics now show the crash cause, reason, fault address, call stack, and program-counter details, with logs saved for review.
- App closing is more consistent across built-in screens. There's now a dedicated function, and the old _emit() function is made private.
- Crash diagnostics no longer display a QR code without a call stack.
- Improved memory allocation for unrestricted requests.
