chore: 导入 Simba-OmniInfantry 基线(云台/底盘双工程)

- 云台(ROBOT_TYPE_GIMBAL)与底盘(ROBOT_TYPE_CHASSIS)完整固件源码 - 新增根级 .gitignore,排除 Keil MDK-ARM 构建产物(.o/.d/.crf/.axf/.lnp/.map/.htm/.sct/.dep/.iex/.lst 等) 与 *.uvguix.* / DebugConfig/(与机器绑定的 UI 布局) - core.autocrlf=false,避免固件源码在检出时被改动换行符

+/* =============================================================================
+ * pid.c - 位置式/增量式 PID(自 legacy Control/PID 原样移植)
+ * 用法:
+ *   PID_PositionStructureInit(pid, need)             初始化
+ *   PID_PositionSetParameter(pid, kp, ki, kd)        设置增益
+ *   PID_PositionSetEkRange(pid, lo, hi)              误差死区(|ek|在区间内视为0)
+ *   PID_PositionSetOUTRange(pid, lo, hi)             输出限幅
+ *   PID_PositionCalc(pid, now)                       每周期计算,结果在 pid->OUT
+ *   PID_PositionClean(pid)                           清误差与积分(模式切换时)
+ * 注意: 积分无独立限幅,靠输出限幅+死区约束;所有云台/底盘 PID 参数集中在
+ *       robot_param.h,控制周期 2ms(与 legacy 调参时一致,勿随意改周期)
