feat: display path alongside branch in worktree list

[Jercik]

Summary

• Show relative path next to branch name in the interactive worktree selection
• Sort worktree list alphabetically by branch name for easier navigation
• Removed unused get-worktree-branches.ts (now using getWorktreeInfo which already provides both branch and path)
• Updated TypeScript lib to es2023 for toSorted() support

Before:

? Select a worktree to remove:
❯ feature/login
  bugfix/header

After:

? Select a worktree to remove:
❯ bugfix/header (../worktree-remove-bugfix/header)
  feature/login (../worktree-remove-feature/login)

Test plan

• Run node dist/cli.js in a repo with worktrees
• Verify paths are displayed relative to current directory
• Verify worktrees are sorted alphabetically by branch name
• Verify selection still returns correct branch name
