Enhancement: Add Nous Research / Hermes Agent as a provider

Provider request: Nous Research / Hermes Agent

What is it? Nous Research runs a managed AI subscription portal (Nous Portal) that powers Hermes Agent. Users authenticate via OAuth at portal.nousresearch.com and receive usage credits/limits similar to other providers CodexBar already tracks.

Why add it? Nous Portal is a growing subscription tier (OpenAI-compatible endpoint) with monthly credit budgets. Users would benefit from seeing their Nous credit balance and reset windows directly in the menu bar alongside their other providers.

Auth method / endpoints to explore

• Auth: OAuth via Nous Portal (portal.nousresearch.com)
• API base: OpenAI-compatible endpoint; credits/usage likely accessible via the portal dashboard or a /v1/usage style endpoint
• Relevant docs: https://hermes-agent.nousresearch.com/docs/integrations/nous-portal

Precedent Similar to how OpenRouter (API token + usage endpoint) and other portal-based providers are handled. If Nous exposes a /v1/usage or billing RPC endpoint, the integration pattern should be straightforward.

Happy to help test or provide more details about the API surface if the Nous team can share endpoint docs.
