fix(deps): carry the Anthropic streamed-error fix into the pin

agentsfleet/nullclaw#5, folded into this bump rather than trailing it in a
second PR: it completes the same incoherence this branch already fixes, and
both halves have to reach the worker in one deploy or the runner keeps
reporting a transport fault for half its providers.

The OpenAI-compatible stream classified a provider error and dropped the
words. The Anthropic stream never classified it: the payload went to the
SSE line parser, every line skipped, the drain hit end of file, and the
non-zero exit surfaced `CurlFailed`. A mistyped Anthropic model therefore
reported a TRANSPORT failure, pointing triage at the proxy, the resolve
pin, and the egress allowlist for a fault the provider had already
explained in the body.

    before   error.CurlFailed
    after    ApiError: type=not_found_error message=model: claude-...

Verified against this pin: agentsfleet-runner 696 pass / 3 skip / 0 fail.
The nullclaw suite carries both new Anthropic cases (a not-found payload
that must name the model, and a 429 that must keep its status across the
different mapping).
