// Clear any pre-existing text in the terminal input buffer before sending the command.
// Unix (bash/zsh): Ctrl+U (\x15) clears the current line via unix-line-discard.
// Windows (PowerShell): Escape (\x1b) clears the current line in PSReadLine's default Windows edit mode.
// Sending \x1b alone (without a trailing bracket sequence) via a separate sendText call is safe —
// PSReadLine's escape-sequence timeout ensures it is processed as a standalone Escape keypress.
