fix(oc2ov-test): add Context Engine test case and main branch add cron

[kaisongli]

主要变更：

• base_cli_test: smart_wait_for_sync/wait_for_sync 新增 session_id 参数，修复独立session检查错误session的Bug
• base_cli_test: 新增 send_and_retry_on_timeout 方法，处理LLM超时和空响应自动重试
• assertions: extract_response_text 拼接所有payloads而非只取第一个；空payloads时返回空字符串而非str(response)
• test_context_engine: 新增6个Context Engine核心交互测试(assemble/compact/recall/expand/isolation)
• test_memory_crud: TestMemoryRead增加确认步骤和关键词容错；使用独立session_id
• conftest: 更新测试报告描述，覆盖Context Engine交互场景
• run_tests: 更新测试路径配置

Category	Suggestion	Impact
General	Use context managers for HTTP requests Wrap all requests calls in context managers to ensure proper HTTP connection cleanup. This avoids leaving dangling connections open and improves resource management, especially in test environments with many API calls. tests/oc2ov_test/tests/p0/test_context_engine.py [50-76] def list_session_ids(self) -> Set[str]: try: - resp = requests.get(f"{self.server_url}/api/v1/sessions", headers=self.headers, timeout=10) - if resp.status_code != 200: - return set() - sessions = resp.json().get("result", []) - return {s["session_id"] for s in sessions} + with requests.get(f"{self.server_url}/api/v1/sessions", headers=self.headers, timeout=10) as resp: + if resp.status_code != 200: + return set() + sessions = resp.json().get("result", []) + return {s["session_id"] for s in sessions} except Exception: return set() def get_session_detail(self, session_id: str) -> Optional[Dict]: try: - resp = requests.get( + with requests.get( f"{self.server_url}/api/v1/sessions/{session_id}", headers=self.headers, timeout=10, - ) - if resp.status_code == 200: - return resp.json().get("result", {}) + ) as resp: + if resp.status_code == 200: + return resp.json().get("result", {}) except Exception: pass return None Suggestion importance[1-10]: 5 __ Why: Using context managers for HTTP requests is a good practice to ensure proper connection cleanup, improving resource management in tests.

	Wrap remaining requests in context managers Wrap the remaining requests.post and requests.get calls in OVSessionVerifier with context managers for consistent resource cleanup. Apply this to commit_session and poll_task_until_done methods. tests/oc2ov_test/tests/p0/test_context_engine.py [78-108] def commit_session(self, session_id: str) -> Optional[str]: try: - resp = requests.post( + with requests.post( f"{self.server_url}/api/v1/sessions/{session_id}/commit", headers=self.headers, timeout=30, - ) - if resp.status_code == 200: - return resp.json().get("result", {}).get("task_id") + ) as resp: + if resp.status_code == 200: + return resp.json().get("result", {}).get("task_id") except Exception: pass return None def poll_task_until_done(self, task_id: str, max_wait: int = TASK_POLL_MAX_WAIT) -> Optional[Dict]: start = time.time() while time.time() - start < max_wait: try: - resp = requests.get( + with requests.get( f"{self.server_url}/api/v1/tasks/{task_id}", headers=self.headers, timeout=10, - ) - if resp.status_code == 200: - task_data = resp.json().get("result", {}) - status = task_data.get("status", "unknown") - if status in ("completed", "failed"): - return task_data + ) as resp: + if resp.status_code == 200: + task_data = resp.json().get("result", {}) + status = task_data.get("status", "unknown") + if status in ("completed", "failed"): + return task_data except Exception: pass time.sleep(TASK_POLL_INTERVAL) return None Suggestion importance[1-10]: 5 __ Why: Consistent use of context managers for all requests in OVSessionVerifier ensures uniform resource cleanup, aligning with best practices.
