Two follow-ups to the M3 default-aux-model PR (#37664):

1. AUTHOR_MAP entry: add fearvox1015@gmail.com -> Fearvox so the
   check-attribution CI job recognises Nolan's real contributor
   email. The previous run of the attribution check on #37664
   failed because the commit was authored as nolan@0xvox.com
   (wrong local git config) which isn't in AUTHOR_MAP. The
   commit itself is now re-authored to fearvox1015@gmail.com
   so both the per-commit check and the AUTHOR_MAP lookup pass.

2. tests/hermes_cli/test_api_key_providers.py::TestMinimaxOAuthProvider
   ::test_minimax_oauth_aux_model_registered was pinning the aux
   model in the legacy _API_KEY_PROVIDER_AUX_MODELS dict, which
   the PR correctly removed (mirrors the deepseek cleanup in
   773a0fa). The test now asserts the new world order: the
   aux model comes from ProviderProfile.default_aux_model on
   the minimax-oauth profile, not the fallback dict. This is
   the same pattern that the profile-layer deepseek fix
   introduced.

Three Copilot inline review comments on #37664, two worth landing
in a polish pass before merge:

1. auxiliary_client.py:270 — Copilot suggested keeping the
   minimax-* entries in _API_KEY_PROVIDER_AUX_MODELS_FALLBACK as
   a safety net for environments where the profile-based
   resolution can't import or run plugin discovery. **Declined.**
   The deepseek precedent (commit 773a0fa) explicitly removed
   deepseek from the same dict for the same reason — the profile
   layer is the source of truth and the dict is a legacy
   pre-profiles-system fallback. We do not want to fragment the
   codebase by provider: either the profile layer is authoritative
   or the dict is. The minimax PR picks profile (matching deepseek)
   and the dict stays cleaned up. The risk Copilot raises is
   real but theoretical — plugin discovery runs at import time of
   the providers module, which is the first thing any modern
   Hermes entrypoint imports.

2. tests/agent/test_minimax_provider.py:162 — Copilot flagged
   that the test class relies on _get_aux_model_for_provider()
   resolving via provider profiles but doesn't explicitly trigger
   plugin discovery. **Fixed.** Added 'import model_tools  # noqa:
   F401' at the top of both test_minimax_aux_is_standard and
   test_minimax_aux_not_highspeed. The fixtures in the parallel
   test_minimax_profile.py already did this; the legacy test in
   test_minimax_provider.py was order-dependent and would silently
   break if anyone reorganised the test ordering. Pinned the
   dependency explicitly so the test is order-independent.

3. tests/plugins/model_providers/test_minimax_profile.py:46 —
   Copilot flagged that the docstring referenced a hard-coded
   line number 'hermes_cli/models.py:298' that would go stale.
   **Fixed.** Replaced with the symbol reference
   'hermes_cli.models._PROVIDER_MODELS[\'minimax\']' which is
   stable under file edits and grep-friendly. The new docstring
   also reads more naturally — readers don't have to look up
   'what's at line 298' to follow the reasoning.

All 221 minimax-related tests still pass.
