feat(config): add RoutingConfig to AgentDefaults

Browse source 
Introduce RoutingConfig with three fields:
  - enabled: activates per-turn model routing
  - light_model: references a model_name in model_list
  - threshold: complexity score cutoff in [0,1]

When routing.enabled is true and the incoming message scores below
threshold, the agent switches to light_model for that turn. Absent or
disabled config leaves existing behaviour completely unchanged.

Example:
  "agents": {
    "defaults": {
      "model": "claude-sonnet-4-6",
      "routing": {
        "enabled": true,
        "light_model": "gemini-flash",
        "threshold": 0.35
      }
    }
  }

// RoutingConfig controls the intelligent model routing feature.

// (message length, code blocks, tool call history, conversation depth, attachments).
