feat(kilo): fetch free models from Kilo API + Windows build fixes (#455)

- Add /api/providers/kilo/free-models endpoint with 1hr cache
- Fetch and merge Kilo free models with hardcoded models for kilocode provider
- Display 'Free' badge on models fetched from Kilo API
- Fix Windows build: add cross-env, remove --webpack flag, add turbopack config
- Add outputFileTracingExcludes for Windows system directories
