Multi-model routing — Guardian-specific model assignment

[frankxai]

Each Guardian routes to their optimal model:

• Shinkami (Source) → Claude Opus (synthesis, meta-reasoning)
• Draconia (Fire) → Claude Sonnet (fast action, code generation)
• Lyria (Sight) → Gemini Pro (vision, multimodal analysis)
• Leyla (Water) → Claude Haiku (creative flow, rapid iteration)
• Lyssandria (Earth) → Local models (stability, privacy, offline)

Tasks:

• Model routing config in .arcanea/arcanea.jsonc
• Guardian → model mapping with fallback chains
• Cost-aware routing (prefer cheaper models for simple tasks)
• Latency-aware routing (prefer faster models for interactive tasks)

Intelligence OS router wired into runtime (runtime.ts). detectTaskRoute → getGuardian → buildSystemPrompt flow operational. 12 routing rules, 94 tests passing.
