Soliq: multi-provider model routing
The model-routing layer now spans OpenAI, Anthropic, Google, Meta and Mistral with cost-aware fallback chains and provider-specific tuning per task.
- Cost-aware routing (per-token caps, per-app budgets, fallback ladders)
- Provider-specific knobs (Anthropic system tools, OpenAI parallel tool-calls)
- Token accounting dashboard with per-app spend
- 12 prompt-injection defence patterns added to the eval set
