X Title: feat: Experimental annotated argparse by KelvinChung2000 · Pull Request #1666 · python-cmd2/cmd2

Description: Adds @with_annotated, a type-hint-driven alternative to @with_argparser that builds the parser automatically from a command's signature (positional/option inference, enum/literal/path/collection handling, subcommands, groups, mutex). Marked experimental. New module cmd2/annotated.py plus Argument / Option metadata classes exported from cmd2 Underscored param names auto-dasherize in generated flags (dry_run → --dry-run); opt out via Option("--my_flag") Dedicated docs page docs/features/annotated.md with an experimental admonition; argument_processing.md keeps a short pointer Example app examples/annotated_example.py and test suite in tests/test_annotated.py
