The whole provider now lives in plugins/model-providers/solstice/ on the
generic seams:
- auth.py: NAS config discovery plus the brokered exchange/refresh, given
to the generic PKCE flow as token_request. A refresh that NAS rejects
(it folds every Google failure into 502) is treated as a dead grant
needing re-login.
- transport.py: a GeminiNativeClient subclass on the
generateContentPerUserQuota methods with Bearer auth (~30 lines, where
the PR duplicated a 257-line adapter).
- __init__.py: a hidden profile (create_client, fallback models,
default_aux_model).
Removed from core: hermes_cli/solstice.py, agent/solstice_adapter.py, and
the provider's branches in main.py, auth_commands.py, models.py,
runtime_provider.py, model_setup_flows.py and agent_runtime_helpers.py.
The unused SOLSTICE_CLIENT_ID env read is gone too.
