// hexai-tmux-edit opens a tmux popup with $EDITOR for composing AI agent
// prompts. It captures existing prompt text from the target pane, pre-fills
// the editor, and sends the edited text back via tmux send-keys.
//
// Usage:
//
// hexai-tmux-edit [--config <path>] [--agent <name>] [--pane <id>]
//
// Tmux keybinding (add to ~/.tmux.conf):
//
// bind e run-shell -b "cd '#{pane_current_path}' && hexai-tmux-edit --pane '#{pane_id}'"
