## App state
Improved app state management in `LoaderService` and `GuiService`:
- Re-ordered some of the state transitions
- Hardened `GuiService` for repeated events (that might trigger a re-render of an app that's already rendered)
- Validate state transitions in `LoaderService` and crash if an app transitions from the wrong state to the next one.
## LoaderService
- Removed `tt::loader::` functions and expose `LoaderService` interface publicly.
- Implement `stopAll()` and `stopAll(id)` which stops all instances of an app, including any apps that were launched by it.
- Rename `stop()` functions to `stopTop()`
- Created `stopTop(id)` which only stops the top-most app when the app id matches.
- Moved `loader::LoaderEvent` to `loader::LoaderService::Event`
- Changed app instance `std::stack` to `std::vector`
## Improvements
- `ElfApp`: error 22 now shows a hint that `main()` might be missing
- Starting, installing and uninstalling apps now stops any running app (and its children) on the stack
## Bugfixes
- `HttpdReq` out of memory issue now shows an error message and doesn't crash anymore (this would happen on devices without PSRAM with WiFi active, when an app was installed)
- `GuiService::hideApp()` lock should not wait for timeout and now waits indefinitely
- `Buildscript/release-sdk-current.sh` deletes the previous local release before building a new one
## Code correctness
- App classes were made `final`
- Apps that had a `void start()` now have a `LaunchId start()`
- `tt::app::State`: renamed `Started` to `Created` and `Stopped` to `Destroyed` to properly reflect earlier name changes
- Refactor `AppManifest`: add new fields and rename existing ones
- Parse and validate the manifest from an app that is being installed.
- Remove deprecated `scoped()` from `Lock`
- Create `Tactility/Paths.h`
- App loading at boot now properly parses the manifest files of external apps
- Properly lock both source and destination locations during app install
- Remove LVGL path variants from `AppPaths` and `ServicePaths`
- Removed `xPath` base classes for apps and services. There's now `AppPaths` and `ServicePaths`.
- Renamed app and service paths: "data" and "system" paths are now "user data" and "assets"
### Cardputer:
- Fix keyboard issue with up/down button conflict when selecting switch
- Fix backlight flickering
### UI improvements
- Removed a 3 pixel border that went around the entire desktop environment
- Improved system layout (GuiService)
- Statusbar: improved layout (mainly margin/padding)
- Toolbar: fixed margin/padding of all buttons, fixed alignment of all content
- Improved layout/UI of many apps
### Other
- Update LVGL to 9.3.0 official release (was dev version)
- Implement `UiScale` in `hal::Configuration`: small screens with no touch can now opt for a more optimized experience (e.g. Cardputer, Waveshare 1.47, Waveshare 1.3", etc.)
- Fix for Cardputer UART configuration and added I2C configuration
- Fix for software keyboard bug in Gui
- Removed deprecated fields from `hal::Configuration`
- Updated the simulator devices to use the new HAL config
- add `bool tt::hal::hasDevice(Device::Type)`
- Cleanup of `AppList` app code
- Improve `Gpio` app for small screen devices
- Added various ESP32 GCC wrappers to wrap LVGL functions (with manipulations for small screen devices)
- Moved `Launcher` assets to `assets/` subfolder
- Optimized `Toolbar` for small screen devices
- Stop showing `system/` partition in `FileBrowser` because it's read-only and not very useful. Created `config::SHOW_SYSTEM_PARTITION` to override this behaviour.
- Hide apps when their required hardware isn't available (I2C, UART, PowerDevice)
- Fix for `CYD-2432S032C` DPI setting
- Bump version for next release
- Fix default gamma for CYD 2432S032C
- Remember gamma curve setting from Display settings app
- Add UART to Core2 (still has no voltage on Grove port, though)
- LVGL performance improvements: pin to second core and set task priority to "critical"
- Fix build warnings, including deprecations
- Removed deprecated `Thread` constructor
- Fix WaveShare S3 display: Some displays would show a white screen at 12MHz, so I'm putting it back to the
official config values.
- Implemented new app: Serial Console
- `Uart::writeString()`: fixed 2 mutex bugs
- `AlertDialog::start()` with default "OK" button added
- Created `tt::lvgl::defaultLockTime` for re-use
- Removed various usages of deprecated `lvgl::obj_set_style_no_padding()`
- Implemented `hal::uart::getNames()` to list all interface names
- Create `Include/` folder for all main projects
- Fix some issues here and there (found while moving things)
- All includes are now in `Tactility/` subfolder and must be included with that prefix. This fixes issues with clashing POSIX headers (e.g. `<semaphore.h>` versus Tactility's `Semaphore.h`)
- Rename `assets` and `config` partitions to `system` and `data`
- Change partition type from `spiffs` to `fat`, so we can have sub-directories
- Fix crash when doing WiFi scan: Increased system event task size to 3kB.
- Free up IRAM on ESP32 (it was required for the Core2, but I also freed up the same amount for Yellow Board)
- Introduced `Paths` objects that can be retrieved by `AppContext` and `ServiceContext`. Apps and services now have their own relative paths. Assets were re-arranged into the correct paths.
- Rename simulator window title to "Tactility"
- Refactored statusbar widget so it persists icon paths properly (it kept a const char* reference, but didn't copy it, so it crashed when the related std::string was destroyed)
- Created `Partitions.h` to expose some useful variables
- Moved USB config in various `sdkconfig` (it was part of the "default" section, but it shouldn't be)
