1. 定义每个关节的运动范围（最小角/最大角）

"""全对全动态行程扫描与碰撞验证（权威版 v2，多进程并行）
|
||||
|
||||
与旧 travel_sweep.py / real_arm_collision_test.py 的区别（旧脚本漏掉了用户实测到的干涉）：
|
||||
1. 直接在进程内构建当前模型（arm_model_v2_rounded.build()），杜绝 STEP/网格过期；
|
||||
2. 关节轴取自 Joint.rear/.d（human_layout 唯一事实源），与网页查看器逐位一致；
|
||||
3. 检查【全部】零件对 —— 包括相邻关节的零件对与电机模组（旧脚本跳过相邻对，
|
||||
而 P04xP05 / P07xP08 恰恰在关节贴面处被卡死）；
|
||||
4. 单关节双向精扫（粗扫 + 二分）得出真实硬限位；
|
||||
5. 组合姿态扫描：每个关节置于其极限，再扫其余关节，收敛出滑块安全范围；
|
||||
6. 写 docs/travel.json（查看器滑块范围）+ docs/travel_detail.json（逐对明细）。
|
||||
|
||||
并行化（用户要求）：
|
||||
- mp.Pool 每个工作进程独立构建一次模型，角度任务批量分发（imap 保序）；
|
||||
- OCCT 布尔运算 SetRunParallel(True)；
|
||||
- 预剪枝：按关节轴计算每对零件的轴向/径向区间，区间不相交的零件对在该关节的
|
||||
任何角度都不可能碰撞，直接跳过（对单关节扫描是精确安全的）。
