## Title

    [Helicone proxy] Requests rejected: "Must included Bearer in API Key" / "API Key is not well formed" (Helicone-Auth header)

## Body

    Cause (Documented platform behavior): The worker requires Helicone-Auth to contain "Bearer " followed by a key matching Helicone API key patterns.
    
    Fix status: documented_behavior
    
    Limitations:
    - HTTP status code for this path not confirmed from the snippet read.
    
    Other error fragments:
    - API Key is not well formed
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/Helicone/helicone/067d9290acb4f1fc9320e902fc67b4b399b50363/worker/src/lib/RequestWrapper.ts (official_docs, unknown, documented_behavior): validateHeliconeAuthHeader errors when "Bearer " is missing or the key fails the key regex.
