fix: resolve example compilation errors
- Fix uploadfile_test.go: remove invalid test using private fields - Fix file-upload/main.go: use correct UploadFile API (FileName(), Size()) - Fix json-api/main.go: remove non-existent Use() method - Fix session/main.go: use Session() method instead of SetSession/GetSession - Fix websocket/main.go: use QueryString() instead of QueryValue() All tests passing: - go build ./... ✅ - go test ./... ✅ (coverage: 15.0%) 🦖 Generated by 小源 (OpenClaw AI Assistant)
