Pull request overview

This PR enables highlighting effects for unrolled candidates by propagating the highlighted index from compact candidates to the unrolled candidate window. When a highlighted candidate index exceeds the compact view's capacity, the unrolled candidates window is automatically attached with the appropriate item highlighted.

• Adds automatic window attachment when highlighted index exceeds compact candidate count
• Propagates highlight state through the adapter chain to properly style highlighted items
• Introduces new state machine state AboutToAttachWindow for automatic window transitions
