hermes - 💡(How to fix) Fix Preflight compression surfaces Codex OAuth 401 instead of falling back [1 pull requests]

Problem

When Hermes runs preflight context compression with the main provider set to openai-codex, the auxiliary compression call can fail with:

⚠️ Compression summary failed: Error code: 401 - {'error': {'message': 'User not found.', 'code': 401}}. Inserted a fallback context marker.

The user sees this after preflight compression even though the main turn continues.

Expected

In auxiliary.compression.provider: auto, a transient/auth failure from the auto-selected main provider should try the auxiliary fallback chain (for example OpenRouter) before surfacing a hard compression summary failure.

Notes

The current fallback path handles payment, connection, and rate-limit errors for auto auxiliary calls, but not auth errors from the auto-selected main provider.
