add DeepSeek V3 + R1 to model-arena via OpenRouter

83c932f02a5f9916002c8dc484c2a560ebe9c307 · 2026-09-08 14:17:58 -0700 · Steve Abrams

New MODELS entries (openrouter provider, OpenAI-compatible path), openrouter
base URL added to both provider maps, PRICING row, key routed from secrets.
V3 uses the tool loop; R1 uses the design pack (its tool-calling is unreliable).
