+ * Clipboard Image Labels

+ * Adds [Image #N] labels to messages that include pasted images,
+ * matching the Claude Code / Codex visual style.
+ *
+ * Usage:
+ *   - Paste:  Ctrl+V  (Alt+V on Windows)
+ *   - Drag:   drag any image file onto the terminal
+ *
+ * When images are detected, [Image #1], [Image #2], … labels are
+ * appended to the message text so they appear in the conversation
+ * history and are visible to the LLM alongside the actual image data.
+ *
+ * A small notification confirms how many images were attached.
