Third surface for the Ox Alpha stealth reasoning model (after the OpenCode Zen rollout in #91250 and the OpenRouter listing in #91284). Adds stealth/ox-alpha to the curated Nous list and regenerates the docs manifest. Free on the portal ($0/$0), 1M context, 131K max output — verified against the live inference-api.nousresearch.com/v1/models. Provider-agnostic metadata already resolves via the bare ox-alpha slug (DEFAULT_CONTEXT_LENGTHS 1,048,576; reasoning_timeouts 300s floor), and the nous route bills via official_models_api, so no pricing snapshot is needed.
