Спампаваць BrightScript Emulator 2.6.1

This release bumps brs-engine to v2.6.0 and brs-scenegraph to v0.6.0, bringing substantial **Roku OS 16.0** feature coverage. The new **Effect** node adds rounded corners, borders, and linear/radial gradients to Rectangle and Poster, paired with a new **FloatArrayFieldInterpolator** node for animating its array-valued fields and a public ArrayGrid.focusFeedbackPoster field for customizing a grid's focus indicator. The core engine gains a new **roWebSocket** component with full Node.js and browser support, ifDraw2D.Clear() now returns a Boolean like DrawLine()/DrawPoint()/DrawRect() already did, and a new
roTextureRequest.SetDrawable() controls whether a texture-manager bitmap can be drawn onto directly. An undefined conditional-compilation name in #if/#elseif now evaluates to false instead of raising a compile error, matching Roku OS 16.0's relaxed rule. The remote-control simulation also gains **experimental** multi-controller support (multi_controllers=1), an expanded game pad button map, and an analog GetValue() extension on roUniversalControlEvent. Also fixed: DrawScaledObject() not mirroring the image for a negative scaleX/scaleY, a SceneGraph focus re-grab being dropped when the competing focus lived in a still-detached subtree, and DynamicKeyGrid not rendering a Key Definition File's own icon/focusIcon bitmaps.

See the **BrightScript Simulation Engine** v2.6.0 [full changelog](https://github.com/lvcabral/brs-engine/releases/tag/v2.6.0) for all the language and framework features and improvements.
