## Title

    Proposed fix: [Anthropic API] Monthly spend-cap 429 'You have reached your API usage limits' (enforced_spend_limit_reached) has no retry-after; retries loop until next month

## Body

    Recommended action: Check error.details.error_code == enforced_spend_limit_reached (or absence of retry-after) and stop retrying; request a higher tier/limit or raise the self-set spend limit.
    
    Option: Detect spend-cap errors and fail fast [evidence: official_recommended_action]
    Applies when: Clients with automatic retries
    Steps:
    1. Inspect error.details.error_code for enforced_spend_limit_reached
    2. Treat 429 without retry-after as non-retryable
    3. Alert operators; request higher limits in Console or raise the custom spend limit
    Expected: No retry storms; clear operator signal.
    
    Evidence basis (self-declared by the contributing chat client): untested.
