llmkit 0.1.3

//! Integration tests for Phase 5 implementations
//!
//! This test file verifies that all new provider enhancements work correctly:
//! - Phase 1: Extended thinking (Vertex, DeepSeek)
//! - Phase 2: Regional providers (Mistral EU, Maritaca)
//! - Phase 3: Real-time voice (Deepgram v3, ElevenLabs)
//! - Phase 4: Video generation (Runware, DiffusionRouter)
//! - Phase 5: Domain-specific (Med-PaLM 2, Scientific benchmarks)
//!
//! Note: Vertex tests require GCP credentials and are marked #[ignore].
//! Run with: cargo test --features vertex -- --ignored
