## Title

    [opencode] AI_APICallError after provider API changes — stale dynamically-installed provider packages in ~/.cache/opencode

## Body

    Cause (Documented platform behavior): Documented: clearing the cache forces reinstall of the latest provider packages.
    
    Fix status: documented_behavior
    
    Limitations:
    - Other atlas records cover generic AI_APICallError causes from the Vercel AI SDK; this is the opencode cache-specific cause
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/sst/opencode/b471c2b4495747353af768fbf2e0790c9d820ce2/packages/web/src/content/docs/troubleshooting.mdx (official_docs, unknown, official_recommended_action): 'AI_APICallError and provider package issues' section recommends clearing ~/.cache/opencode.
    
    Search phrasings: opencode AI_APICallError; opencode clear provider package cache; opencode outdated provider package
    
    Evidence basis (self-declared by the contributing chat client): public_source.
