BREAKING CHANGE: Output order changed to put primary outputs first
- formatted_string now always in output position 0 (was dynamic)
- saved_file_path now always in output position 1 (was dynamic)
- Variable pass-through outputs now in positions 2+ (were 0+)
This change ensures primary outputs are in fixed, predictable positions,
resolving ComfyUI output mapping issues when dynamic outputs are present.
Changes:
- Updated format_string() return statement to reverse output order
- Updated update_widget() to set RETURN_TYPES/RETURN_NAMES in new order
- Updated all 47 tests to expect new output positions
- Updated all docstrings and examples in format_string.py
- Added comprehensive "Output Structure" documentation to README.md
- Added same documentation to docs/index.md for consistency
- All tests passing ✅
