* feat(tools): always show Nous Tool Gateway backends, login on select
The Nous-managed Tool Gateway rows in `hermes tools` (Firecrawl, OpenAI
TTS, Browser Use, FAL image/video) were hidden unless the user was already
logged into Nous Portal with paid access. Now they are always listed.
Selecting one runs an inline Nous Portal device-code OAuth + entitlement
check — auth only, no inference-provider switch and no bulk 'enable all
tools' prompt (that stays in `hermes model`). The row only activates the
gateway once paid access is confirmed.
- _visible_providers: stop hiding managed_nous_feature rows (incl. those
also flagged requires_nous_auth); pure pre-auth UX rows still gate on login
- nous_subscription.ensure_nous_portal_access(): auth + entitlement gate
that preserves the user's active inference provider
- _configure_provider / _reconfigure_provider: run the inline gate for
managed backends; write config only when entitled
- picker marker: 'via Nous Portal (login on select)' for logged-out users
- _hidden_nous_gateway_message: now a no-op (rows are never hidden)
* docs: hermes tools is a first-class Tool Gateway entry point
The Tool Gateway docs framed `hermes setup --portal` / `hermes model` as
the activation path and only mentioned `hermes tools` for mixing in your
own keys. With the inline-login change, picking a Nous-managed backend in
`hermes tools` is a complete path on its own — it logs you into Nous
Portal on select if needed, without switching your inference provider or
prompting to enable every other tool.
- tool-gateway.md: Get started now lists three peer entry points; new
paragraph explaining login-on-select and the no-prompt fast path when
OAuth is already active
- nous-portal.md + run-hermes-with-nous-portal.md: note that managed rows
appear logged-out and trigger inline login on select
