refactor: 清除 core/plugins 全局状态依赖，ProgressManager 缓存引用 (Phase 5)

- core/alive_scanner.go: GetFlagVars() → session.Params
- core/service_scanner.go: GetFlagVars() → session.Params 和 config.Target.Ports
- common/progress_manager.go: 缓存 State 和 NoColor 到字段，不再运行时读全局
- common/output_api.go: SaveResult 改用 GetGlobalConfig().Output.DisableSave
- common/network.go: WrapperTcpWithTimeout 标记 Deprecated
- core/ 和 plugins/ 下已无全局状态调用残留

common/progress_manager.go
