06730fe05c feat: Implement synthetic edges city↔airport (Task 10) 
- Add TransferTime constants (AirportToCity, CityToStation, StationToStation)
- Update Edge struct with Synthetic field
- Enhance addSyntheticEdgesForNode to use constants and mark synthetic edges
- Update BuildGraphFromStations to set Synthetic field
- Mark synthetic edges in GeoJSON output as dashed lines
- Write TestSyntheticAirportCityEdges and TestRouteWithSyntheticAirportCityEdges tests

6ae491ef1c feat: Implement basic caching layer with cache-aside pattern for /search results 
- Implement cache-aside pattern via SearchCacheService in RouteSearch handler
- Add TTL policies: 3 hours near-term, 7 days far-term
- Write TestCacheAsideSearch and variants for TTL verification
- Extend CacheAside to fully implement Cache interface (Get, Set, Exists, Delete, Increment, Decrement)

4de50f4948 feat: Implement on-demand /search integration in lazy graph expansion 
- Integrate on-demand Yandex /search calls in FindRoute when lazy expansion + synthetic fallback fails
- Add real route segments from API response as edges, then retry BFS search
- Integrate existing cache key generation and TTL policies (SearchNearTermTTL: 3h, SearchFarTermTTL: 7d)
- Write tests: TestSearchRoutes_onDemand, TestSearchRoutes_onDemandVerifyIntegration, TestFindRouteWithSyntheticFallback
- All tests pass before task 5 (transfer depth limiting)

26c4be2d3a feat: implement synthetic edge fallback in FindRoute

- Modify FindRoute to add synthetic edges as fallback when no route found
- Write TestFindRouteWithSyntheticFallback test
