Bridge parent CompositionLocals into Tao window scenes

Capture the outer currentCompositionLocalContext in TaoDecoratedWindowAdapter
and re-provide it inside the fresh ComposeScene Tao opens per window so
themes (Jewel/Material), density, layout direction and user-provided locals
flow across the scene boundary — matching Dialog/Popup behavior and removing
the need to wrap content with IntUiTheme twice when using NucleusBackend.Tao.

Rename SingleInstance.kt to match its single top-level declaration.
