FR-2 RoutingPolicy: - RoutingPolicy + RoutingRule dataclasses in llm_connect/routing.py - resolve(task_type, estimated_cost_per_1k=None) with cost-cap fallback - Exported from llm_connect.__init__; contract doc at contracts/functional/routing-policy.md - 11 tests covering rule match, cost-cap, fallback, unknown type, no-match FR-1 HTTP serve mode: - LLMServer in llm_connect/server.py (stdlib http.server, zero extra deps) - POST /execute + GET /health; CLI via python -m llm_connect.server - [server] optional-dep group added to pyproject.toml - Contract doc at contracts/functional/server.md - 9 tests: health, round-trip, 400/404/500 errors, config forwarding - Added "mock" provider to factory for CLI default All 101 tests pass.
