* Fixed MouseGrabView bug.
Added extensive test coverage for `Keyboard`, `Mouse`, `Timeout`, and `Popover` functionalities, including edge cases and concurrent access. Introduced parameterized and data-driven tests to reduce redundancy and improve clarity.
Refactored codebase for modularity and maintainability,
introducing new namespaces and reorganizing classes. Enhanced `MouseImpl`, `KeyboardImpl`, and `Runnable` implementations with improved event handling, thread safety, and support for the Terminal.Gui Cancellable Work Pattern (CWP).
Removed deprecated code and legacy tests, such as `LogarithmicTimeout` and `SmoothAcceleratingTimeout`. Fixed bugs related to mouse grabbing during drag operations and unbalanced `ApplicationImpl.Begin/End` calls. Improved documentation and code readability with modern C# features.
* Code cleanup.
* Update Tests/UnitTestsParallelizable/Application/Runnable/RunnableIntegrationTests.cs

* Improve null handling and simplify test setup
In `MouseImpl.cs`, added an early `return` after the `UngrabMouse()`
call within the `if (view is null)` block to prevent further execution
when `view` is `null`, improving null reference handling.
In `RunnableIntegrationTests.cs`, removed the initialization of the
`IApplication` object (`app`) from the `MultipleRunnables_IndependentResults`
test method, simplifying the test setup and focusing on runnable behavior.
* Code cleanup
* API doc link cleanup
