refactor(cli): derive relaunch flag table from argparse introspection

Browse Source 
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).
- _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).
- test_ignore_user_config_flags.py: brittle inspect.getsource grep
  replaced with proper parser introspection.
- test_relaunch.py: introspection sanity tests added.

Salvaged from PR #17549; added top-level -t/--toolsets flag to
_parser.py so #17623 (fix(tui): honor launch toolsets) behavior is
preserved on current main.
