Pull the top-level + chat parser construction out of main() into hermes_cli/_parser.py so relaunch.py can introspect parser._actions to discover which flags exist and whether they take values, instead of maintaining a parallel hand-rolled (flag, takes_value) tuple list. - _parser.py: build_top_level_parser() returns (parser, subparsers, chat_parser); side-effect-free import. - main.py: ~290 lines of inline parser construction collapsed to a helper call. Other subparsers stay inline (dispatch is bound to module-level cmd_* functions). - test_ignore_user_config_flags.py: brittle inspect.getsource grep replaced with proper parser introspection. - test_relaunch.py: introspection sanity tests added. - _parser._inherited_flag(parser, ...): wraps parser.add_argument and sets action.inherit_on_relaunch = True. Used in place of parser.add_argument for the 25 flags (top-level + chat) that need to carry over. - _parser.PRE_ARGPARSE_INHERITED_FLAGS: holds --profile/-p, which isn't on argparse (consumed earlier by main._apply_profile_override). - relaunch.py: drops _CRITICAL_DESTS and _PRE_ARGPARSE_FLAGS; the table builder now filters by getattr(action, "inherit_on_relaunch", False). Renames _CRITICAL_FLAGS_TABLE / _build_critical_flag_table / _extract_critical_flags / preserve_critical= → _INHERITED_FLAGS_TABLE / _build_inherited_flag_table / _extract_inherited_flags / preserve_inherited= so the terminology is consistent.

Top-level argparse construction for the hermes CLI.

Only the top-level parser and the ``chat`` subparser live here. Every other

subparser (model, gateway, sessions, …) is built inline in ``main.py``
