feat: support pixel-precision mouse reporting (CSI ?1016h)

Adds a new MouseFlags value, MousePixelEvents, that acts as a modifier on top of MouseButtonEvents/MouseDragEvents/MouseMotionEvents. When set, EnableMouse emits PmMouseSgrPixel instead of PmMouseSgr and the input parser skips its cell-size clamp on mouse coordinates so pixel positions pass through to EventMouse.Position() unchanged. Default behavior is unchanged.

Includes tests pinning both the existing clip behavior and the new pixel-mode passthrough including the toggle-off transition.
