fix: allow interactive prompts to access terminal

[timvw]

Summary

Fixes the hanging issue with interactive selection commands (wt co, wt rm, wt pr, wt mr).

Problem

The shell function wrapper was capturing all output with output=$(command wt "$@"), which broke promptui's interactive selection by preventing it from accessing the terminal directly.

Solution

Modified the shell function to detect when commands need interactive mode (single argument matching co|checkout|rm|remove|pr|mr) and execute them directly without output capture, while still maintaining auto-cd functionality for commands with arguments.

Test plan

• Verify wt co shows interactive branch selector
• Verify wt rm shows interactive worktree selector
• Verify wt pr shows interactive PR selector (requires gh CLI)
• Verify wt mr shows interactive MR selector (requires glab CLI)
• Verify wt create foo still auto-navigates to worktree directory
• User needs to reload shell integration after merge: source ~/.zshrc
