Ishaan Jaffer be2d1ad678 feat(proxy): add Routing Groups — named routing pipelines with live tester UI 
New first-class concept: a routing group is a named, persisted pipeline that
combines model deployments with a routing strategy (priority-failover, weighted,
latency-based, cost-based, etc.).

Backend:
- LiteLLM_RoutingGroupTable Prisma model
- 9 new Pydantic types in litellm/types/router.py
- CRUD + test + simulate REST endpoints at /v1/routing_group
- RoutingGroupTestEngine + RoutingTraceCallback for live testing
- Startup sync: active groups are loaded from DB and wired into the LLM router
- priority-failover: tiered model groups + fallback chain
- weighted: per-deployment weight passed through to simple_shuffle

UI:
- Routing Groups page + sidebar entry
- Builder modal: strategy picker, deployment list with priority/weight controls
- Table with delete/test actions
- Live Tester: animated SVG traffic flow diagrams
  - OrderedFallbackFlow (vertical cascade, dashed red fail arrows)
  - WeightedRoundRobinFlow (fan-out bezier streams, thickness ∝ traffic %)
  - StatsBar, DeploymentCard, AnimatedStream components
  - Simulation controls (N requests, concurrency, mock/real toggle)

Testing for litellm/

This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.

The point of this is to:

  1. Increase test coverage of litellm/
  2. Make it easy for contributors to add tests for the litellm/ package and easily run tests without needing LLM API keys.

File name conventions

  • litellm/proxy/test_caching_routes.py maps to litellm/proxy/caching_routes.py
  • test_<filename>.py maps to litellm/<filename>.py
