Client contract result/error mapping foundation completed in 1 review loop with final verdict PASS.

## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_cloud_G06_0.log` | `code_review_cloud_G06_0.log` | PASS | `AltApiResult<T>`, `AltApiError`, transport failure kind, and shared response error extraction helper were implemented and verified. |

## 구현/정리 내용

- Added UI-copy-free client core result/error types in `apps/client/lib/src/contracts/alt_api_result.dart`.
- Added `altResponseError` to extract populated `ErrorInfo` from supported market/backtest responses without touching generated protobuf output.
- Added focused Flutter tests for error mapping, result variants, exhaustive switching, supported response extraction, unset errors, and unsupported types.
