fix: Improve CLI flag validation for single-word flags

Fix issue with kebab-case validator incorrectly flagging single-word flags like --prompt. Refactor detectCamelCaseFlags to properly handle all single-word flags. Update tests to verify correct behavior with single-word and camelCase flags. Add support for alternative flag formats in init command (e.g., -my_name). This fixes a bug where users couldn't use the --prompt flag directly and had to use -p instead.
