reedline 0.47.0

// Semantic prompt interactive example
// Run with: cargo run --example semantic_prompt_interactive
//
// This example demonstrates OSC 133 semantic prompt markers.
// Use this with Ghostty's "Overlay Semantic Prompts" debug feature
// to visually verify marker placement.
//
// The expected sequence on screen is:
//   [A;k=i][left prompt][indicator][B][user input area][P;k=r][right prompt]
//
// Where:
//   A;k=i = Start of primary prompt (interactive)
//   B     = Start of user input area (end of prompt)
//   P;k=r = Right prompt marker
