- Add parseAppFlagsString() in AppManifestParsing.cpp to parse comma-separated flags (HideStatusBar, Hidden, None)
- Parse [app]flags in V1 and app.flags in V2 manifests
- Loader already supports HideStatusBar, GuiService hides statusbarWidget when set
- Enables fullscreen for ELF apps (e.g. BibleVerse, BookPlayer) without firmware recompilation of internal manifests
- Add tests for flag parsing (38 tests passing)
- Tested on es3c28p /dev/cu.usbmodem1101 @ 192.168.68.133 with HelloWorld app
PR #550 moved TestFile.h from Tests/TactilityCore to Tests/Tactility, but
AppManifestParsingTest.cpp and PropertiesFileTest.cpp still include the old
path, so the test build fails on main.
* **New Features**
* Added public accessors for querying module/device start and ready state.
* **Refactor**
* Internal state moved to opaque internal objects; module/device/driver initializers now explicitly initialize internal pointers.
* Lifecycle handling updated to construct/destruct internal state and use accessors.
* **Tests**
* Tests updated to use public accessors and explicit construct/destruct lifecycle calls.
* **Chores**
* Test build/include paths and small metadata updated.
