fix: 全链路审查结果过滤，防止解析失败和异常数据泄漏到最终结果

- grammar_check_reviewer: 修正 details["name"] 从 sensitive_word_check 改为 grammar_check
- inter_tool._create_issue_item: 验证 dict 至少含 issue_point/location/suggestion 一个有意义字段
- inter_tool.parse_ai_review_response: 异常处理改为 exist_issue=False
- ai_review_workflow Phase 5: 兜底过滤增加字符串 check_result 检查
