Security:
- Enforce client_max_body_size in HTTP/2 and HTTP/3 adapters before buffering
- Use trusted-proxy-aware client IP extraction for access control and rate limiting
- Include Host and Vary headers in proxy cache key to prevent cache poisoning
- Harden static file path traversal check with filepath.Clean + prefix validation
- Honor proxy_ssl config for WebSocket upstream TLS
Proxy/handler bugs:
- Decrement WebSocket connection count immediately on return (not deferred in retry loop)
- Remove ineffective headersPool
- Coalesce concurrent background cache refreshes with singleflight
Dev/build:
- Fix Makefile run and test-config targets
- Remove broken wget healthcheck from docker-compose
- Add missing integration build tags
- Fix go vet warnings in tests
CI:
- Run golangci-lint and integration tests in Gitea Actions

Apply modern Go patterns across the codebase:
- Replace `interface{}` with `any` (Go 1.18+)
- Use `for range n` instead of `for i := 0; i < n; i++` (Go 1.22+)
- Replace `sort.Slice` with `slices.Sort` from slices package
- Simplify sync.WaitGroup patterns with errgroup where appropriate
- Add Makefile targets for modernize analyzer
