Development record

A runner pointed at a local model leaves the weight fingerprint, quantisation and runtime version out of its record entirely, where the provider adapter's loopback route lists them as not configured; the intent audit of itd-166 (ac-4) found it with the opencode runner on local/qwen3-coder. A runner cannot tell from its own output that a model is served locally, so the fix needs the local pin's notion of which providers are local.
