fix: SAT 临时文件唯一化,修 DGJM.sat 读取越界
1. AcDbX3dSolid::CreateFromSat 的 temp\temp.sat 改为
temp_<pid>_<原子序号>.sat,用完 DeleteFile。原来固定名且从不删除,
两个 CAD 实例同时从 SAT 重建时会互相覆盖。
2. DGJM.sat 的读取统一改成「分配时补终止符 + 按实际读到的长度赋值」:
new char[n] 之后直接赋给 CString 会把未初始化内存当字符串读到终止符,
现在 new char[n+1] + memset,再用 CString(pszTxt, nRead) 明确长度。
涉及 AcDbX3dSolid、AecDbEarthWormFitting、DGJMDlg、GJYXJMDlg、
JMDBDlg、JMSJDlg 共 6 处。
DGJM.sat 本身仍是固定文件名,写读双方靠它隐式传递,本次不改名。
