Subject: [PATCH] feat: stealth/ox-alpha free model in the OpenRouter catalog

Adds OpenRouter's free "Ox Alpha" stealth reasoning model
(stealth/ox-alpha) to the OpenRouter fallback snapshot, plus the
provider-agnostic metadata it needs:

- OPENROUTER_MODELS: free-tier entry (1M ctx)
- DEFAULT_CONTEXT_LENGTHS: ox-alpha -> 1,048,576 (verified against
  OpenRouter live /api/v1/models; without this the slug fell through
  to no match)
- reasoning_timeouts.py: 300s stale floor for ox-alpha and the
  OpenCode Zen twin slug x-preview-f-free (reasoning model,
  long-horizon agentic work per its model card)
- model-catalog.json regenerated

Pricing snapshot skipped: openrouter bills via official_models_api
(live pricing; model is free anyway).
