fix: allow interactive prompts to access terminal in shell function

The shell function wrapper was capturing output which broke promptui's
interactive selection for commands like 'wt co', 'wt rm', 'wt pr', 'wt mr'.

Now detects when these commands are run without arguments and executes
them directly without output capture, preserving terminal access for
interactive prompts while still maintaining auto-cd functionality for
commands with arguments.
