feat: 完善扫描器、exec 及 schema 相关功能
- exec/scanner: 用 *interface{} 替换 **json.RawMessage 扫描目标,兼容 DuckDB 返回 map[string]interface{} 的场景;新增 toJSONRawMessage 转换函数
- exec/scanner: ScanVal 支持结构体指针,通过 JSON 中间层转换(DuckDB STRUCT 列)
- exec/scanner: 将 *sql.RawBytes 和 *[]byte 的处理从 ScanValContext 移入 scanner.ScanVal
- exec/query_executor: 简化 ScanValContext,移除私有 scan 方法
- exec: 补充 scanner 级别 ScanVal 测试用例
- internal/util/reflect: 重写 SafeSetVarValue,修复非指针 src 及 nil 指针字段的 panic
- internal/util/column_map: 恢复非匿名带标签结构体字段的展开逻辑
- schema: 新增 vector 列类型支持
- engine: 补充 DuckDB 相关配置
- dialect/sqlite3/vtab: 完善虚拟表适配器
- 各方言测试改用 sqlmock 虚拟连接
