Re-add the claude-subscription LiteLLM route — confirmed working for the real CLI

Earlier this session I removed this route after a curl-based test got
rejected by Anthropic and concluded OAuth subscription forwarding doesn't
work through a proxy at all. That conclusion was wrong: the real `claude`
CLI binary, with ANTHROPIC_BASE_URL pointed at litellm, successfully
completed a request billed against the subscription. The earlier curl test
just didn't replicate whatever header/fingerprint Anthropic requires from
genuine Claude Code CLI traffic — LiteLLM relays that fine when the real
CLI is the caller, but a hand-built request from any other client (Hermes
included) still gets rejected the same way curl did.
