Extract common code patterns into reusable helper functions to improve maintainability and reduce code duplication. Changes: - Extract sanitize_name() for branch name sanitization (4 duplicates removed) - Extract get_worktree_dir() for worktree path calculation (3 duplicates removed) - Extract get_symlink_path() for symlink path calculation (3 duplicates removed) - Extract init_wt_directory() for .wt directory initialization (3 duplicates removed) - Extract create_worktree() for worktree creation logic (3 duplicates removed) - Extract create_symlink() for symlink creation with force option (3 duplicates removed) - Extract run_setup_script() for setup script execution (2 duplicates removed) - Add worktree_exists() helper for future extensibility Benefits: - Code reduction: 613 lines → 560 lines (-53 lines, 8.6% reduction) - Improved maintainability: Changes only need to be made in one place - Better readability: Commands are more concise and easier to understand - Consistency: All commands use the same underlying logic - Bug prevention: Reduces risk of inconsistent updates across duplicated code All existing functionality preserved and tested. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Summary
Apply the DRY (Don't Repeat Yourself) principle to the
wtscript by extracting common code patterns into reusable helper functions. This refactoring improves maintainability, readability, and consistency across the codebase.Changes
Helper Functions Extracted
sanitize_name()- Branch name sanitization (removed 4 duplicates)get_worktree_dir()- Worktree directory path calculation (removed 3 duplicates)get_symlink_path()- Symlink path calculation (removed 3 duplicates)init_wt_directory()-.wtdirectory structure initialization (removed 3 duplicates)create_worktree()- Worktree creation logic (removed 3 duplicates)create_symlink()- Symlink creation with force option (removed 3 duplicates)run_setup_script()- Setup script execution (removed 2 duplicates)worktree_exists()- Worktree existence check helper (for future extensibility)Refactored Commands

This is a pure refactoring - no functional changes or new features added. All existing behavior is preserved.
