Integrate SDL3 controller support and wire it into the InputRouter.
- Add ControllerInputService (src/ControllerInputService.{h,cpp}) to discover, poll and translate SDL3 gamepad events into InputRouter actions, with axis repeat handling and debouncing.
- Update CMakeLists to find or fetch SDL3, add the new source files to the target, link the SDL3 target, and copy runtime DLLs on Windows.
- Add triggerAction(Action) to InputRouter and use it from existing keyboard handling to centralize action dispatch.
- Instantiate ControllerInputService in main so controllers feed the InputRouter.
- Update QML views (ShellWindow, HomeView, LibraryView, SettingsView) to use numeric action IDs and add small UI/status text and navigation tweaks for controller-driven flows.
These changes enable gamepad/controller input for Bigscreen via SDL3 and adapt UI code to handle the mapped actions.
Add a native Qt "Bigscreen" shell: CMakeLists, C++ entry (main.cpp, InputRouter), QML module (Theme, ShellWindow, views and components) and a Bigscreen/.gitignore; update top-level .gitignore and README with Qt build/run instructions. Remove the legacy Tauri/web prototype files (package.json, package-lock.json, src-tauri and many web assets) as part of the migration to the Qt/CMake-based shell.
Add comprehensive READMEs for Bigscreen and Desktop modes, and relocate the Tauri frontend prototype into a new Bigscreen/ subdirectory. This moves package.json/package-lock, src, src-tauri, assets, views, styles and related files into Bigscreen/ to separate the controller-first shell from top-level docs. Update the root README.md to reframe the project as "NebulaOS", describe Bigscreen/Desktop modes, the vision, tech stack and development notes. This reorganizes the repo layout for clearer mode separation and documentation.
