fix(nous): use curated model list instead of full API dump for Nous Portal (#3867)

All three Nous Portal model selection paths (hermes model, first-time
login, setup wizard) were hitting the live /models endpoint and showing
every model available — potentially hundreds. Now uses the curated
_PROVIDER_MODELS['nous'] list (25 agentic models matching OpenRouter
defaults) with 'Enter custom model name' for anything else.

Fixed in:
- hermes_cli/main.py: _model_flow_nous()
- hermes_cli/auth.py: _login_nous() model selection
- hermes_cli/setup.py: post-login model selection
