- Updated README.md screenshots and intro text
- 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.

- GPS settings safely refresh their device list when their window is hidden or its widgets are destroyed.
Graphics & rendering
- Implement `binfont-module` to generate bitmap fonts on the device itself

Boot
- Split up `Tactility.cpp` and its `run()` function into various `Init*.cpp` files.

UX & UI
- USB Settings app: remove border from the button container
New features:
- SDK version 7.0.0 packages include version metadata and platform-specific application settings.
- Apps gain POSIX support for file polling, terminal attributes, and standard input/output, plus additional C and POSIX functions.
- Shell commands can launch installed headless apps using their registered app settings.
- Apps can exit with a status code, and terminal clear commands support clearing from the cursor to the end, from the start through the cursor, or the entire display.
Fixes:
- SDK integration builds locate the build tool reliably and use settings for the selected platform.
- ESP32 file operations handle invalid paths and existing directories more consistently.
- Refactored shell parsing so that the callstack doesn't increase when script complexity increases.

- Moved WiFi logic from `TactilityKernel/` to `wifi-module`
- Created commandline app to control Wi-Fi
- Update `tactility.py` to v6.1.0 so it can be executed directly
DTS modules (device modules) often have a single source file with an empty `struct Module`.
The module's yaml file now allows a `dts-only` boolean to be set, so the source file becomes optional.
`devicetree.yaml` is renamed everywhere to `module.yaml`
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`

- `AppManifest` usage safety improved: pass by value where needed, or use `AppId` instead of a manifest.

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: Add toolbar button that shows alert dialog with info about using favourites
