chore(models): OpenRouter and Nous pickers drop the undated deepseek-v4-flash in favor of the 0731 snapshot

The bare deepseek/deepseek-v4-flash slug is the pre-snapshot release; both
aggregators now carry deepseek-v4-flash-0731 (and Nous exposes the rolling
~deepseek/deepseek-v4-flash-latest alias). Keeping both rows in the curated
picker just duplicates the flash tier.

- OPENROUTER_MODELS (derives the nous list): drop deepseek/deepseek-v4-flash
- model-catalog.json regenerated

Deliberately KEPT: alibaba-token-plan / opencode-go / commandcode / deepseek
direct plugin fallback_models + default_aux_model (bare id is the wire slug
those providers serve), DEFAULT_CONTEXT_LENGTHS / reasoning floor / pricing
snapshot entries (manually-typed id still behaves), and the
deepseek-chat/deepseek-reasoner -> deepseek-v4-flash alias normalization.
