modifies it, they must release their source code under the same license.

94322ceff4 feat: Valkey cache for search results 
- Add internal/cache package using go-redis/v9 (Valkey-compatible)
- Cache keys are deterministic SHA-256 hashes of search parameters
- Cache wraps the Search() method: check cache → miss → execute → store
- Gracefully disabled if Valkey is unreachable or unconfigured
- Configurable TTL (default 5m), address, password, and DB index
- Environment variable overrides: VALKEY_ADDRESS, VALKEY_PASSWORD,
  VALKEY_DB, VALKEY_CACHE_TTL
- Structured JSON logging via slog throughout cache layer
- Refactored service.go: extract executeSearch() from Search() for clarity
- Update config.example.toml with [cache] section
- Add cache package tests (key generation, nop behavior)

385a7acab7 feat: concurrent engine execution with graceful degradation 
- Run all local engines in parallel using goroutines + sync.WaitGroup
- Individual engine failures are captured as unresponsive_engines entries
  instead of aborting the entire search request
- Context cancellation is respected: cancelled engines report as unresponsive
- Upstream proxy failure is also gracefully handled (single unresponsive entry)
- Extract unresponsiveResponse() and emptyResponse() helpers for consistency
- Add comprehensive tests:
  - ConcurrentEngines: verifies parallelism (2x100ms engines complete in ~100ms)
  - GracefulDegradation: one engine fails, one succeeds, both represented
  - AllEnginesFail: no error returned, all engines in unresponsive_engines
  - ContextCancellation: engine respects context timeout, reports unresponsive

dc44837219 feat: build Go-based SearXNG-compatible search service 
Implement an API-first Go rewrite with local engine adapters, upstream fallback, and Nix-based tooling so searches can run without matching the original UI while preserving response compatibility.
