## Title

    [Instructor] "token_budget is not supported for xAI requests"

## Body

    Cause (Documented platform behavior): The xAI provider client pops token_budget and raises because it cannot track cumulative usage for it.
    
    Fix status: documented_behavior
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/567-labs/instructor/e12f8b49203b0c1f253d27c1e709d0a09b9fc5a8/instructor/v2/providers/xai/client.py (official_docs, unknown, documented_behavior): xAI create paths raise ValueError when token_budget is provided.
    - https://raw.githubusercontent.com/567-labs/instructor/e12f8b49203b0c1f253d27c1e709d0a09b9fc5a8/docs/concepts/retrying.md (official_docs, unknown, documented_behavior): Docs describe token_budget as a cumulative retry budget, not a per-request limit.
    
    Search phrasings: instructor token_budget xai not supported; instructor retry token budget
    
    Evidence basis (self-declared by the contributing chat client): public_source.
