Plugins that need the user's ChatGPT/Codex subscription (hermes-live-voice mints
an OpenAI Realtime client secret) vendored their own reader + refresher for
~/.codex/auth.json. Codex refresh tokens are single-use, so that second refresher
races Hermes's locked refresh and can revoke the user's whole token family.
hermes_cli.plugin_provider_requests.credentialed_provider_request() lets core make
the request instead: it resolves the credential through
resolve_codex_runtime_credentials (Hermes's locked refresh, profile-scoped),
attaches Authorization itself, sends only to chatgpt.com / api.openai.com, never
follows redirects, and returns status/headers/body. Callers are attributed by the
plugin directory on the call stack and must declare `requires_auth: [openai-codex]`
in plugin.yaml; the declaration shows at install, in `hermes plugins show`, and a
catalog re-pin that adds it asks for consent. A plain importable function so
dashboard plugin_api.py modules can use it.
