chengyongru ff6b014a07 refactor: allow model/context_window_tokens override in from_config()
- Pop model and context_window_tokens from extra kwargs before
  forwarding to __init__, allowing callers like _run_gateway to
  pass snapshot-derived values instead of config defaults
- _run_gateway now explicitly passes model/context_window_tokens
  from provider_snapshot to preserve pre-refactor behavior
