fix(litellm): gate tests on server feature to fix bare cargo test

The litellm test module uses server-only structs (ActivityModelEntry, SpendModelEntry) that are behind #[cfg(feature = "server")]. Gate the test module with #[cfg(all(test, feature = "server"))] so bare cargo test (without --features server) compiles. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Sharang Parnerkar	8aa7c4c33c	fix(litellm): gate tests on server feature to fix bare cargo test All checks were successful CI / Format (push) Successful in 3s Details CI / Clippy (push) Successful in 2m55s Details CI / Security Audit (push) Has been skipped Details CI / Tests (push) Has been skipped Details CI / Deploy (push) Has been skipped Details CI / E2E Tests (push) Has been skipped Details The litellm test module uses server-only structs (ActivityModelEntry, SpendModelEntry) that are behind #[cfg(feature = "server")]. Gate the test module with #[cfg(all(test, feature = "server"))] so bare cargo test (without --features server) compiles.

Also includes: replace Ollama with LiteLLM proxy, update config, docker-compose, and provider infrastructure. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-02-26 18:23:46 +01:00
