- add CommandExecutor to unify shared command execution lifecycle
across Falyx and standalone command execution
- add CommandRunner for running a single Command directly as a CLI
or programmatic entrypoint
- add Command.build() factory and rename parse_args() to resolve_args()
to clarify the parsing-to-execution boundary
- introduce ExecutionOption and wire execution-scoped flags into
CommandArgumentParser and Command construction
- refactor Falyx to use FalyxParser/ParseResult and CommandExecutor
instead of the older argparse-based flow and run_key path
- simplify __main__.py bootstrap by building a bootstrap Falyx instance
directly and running flx.run()
- improve completer support for preview commands and unique-prefix
command resolution
- default BottomBar toggle namespace to "default"
- expand module/class docstrings to reflect the new execution architecture
