feat(thermal): task-level three-mode thermal switch (off/steady/coupled)

- Backend: thermal_mode field flows from CreateTaskRequest/start-simulation into task.json
- Executor: execute_task reads task.thermal_mode, passes through adapter.run_point to solver
- Solver: run_single_point gains thermal_mode param + coupled branch (do_magnetic_thermal_calculation)
- Frontend: TaskManager three-mode radio with per-mode cost hints, default steady
- Verified: coupled mode end-to-end PASS (TEST-062), temp_rise +29.91, thermal_resistance +2.058

+
+**需求**：工程师自主选择热仿真模式——仅电磁（最快）/ 电磁+稳态热（默认）/ 磁热耦合（精算），
+开关放在任务级（不是执行器全局开关）。
+
+**thermal_mode 三档实现（off/steady/coupled）**：
+- 后端：task_manager.create_task 加 thermal_mode 参数写入 task_payload；tasks.py CreateTaskRequest
+  加 Literal 校验；plans.py start-simulation 加可选 StartSimulationRequest（thermal_mode 默认 steady）。
+- 执行器：task_executor.execute_task 读 task["thermal_mode"] 存 self._current_thermal_mode，
+  _run_simulation_point 传给 adapter.run_point。
+- 适配器：MotorCADAdapter.run_point 加 thermal_mode 透传；基类 SimulationAdapter.run_point
+  加 thermal_mode=None（mock adapter 忽略）。
+- Solver：RobustMotorCADSolver.run_single_point 加 thermal_mode 参数 + coupled 分支
+  （do_magnetic_thermal_calculation 代替"电磁+稳态热"两步）；__init__ 加 thermal_mode
+  （None=从 enable_thermal 推断，向后兼容）。优先级：调用级 > 实例级 > enable_thermal 布尔。
+- 前端：TaskManager.vue 任务创建表单加"热仿真模式"三档单选（含各档耗时提示），默认稳态热。
+
+**git 远程推送（gogsgit.ez4l.com）**：
+- 远端地址确认：https://gogsgit.ez4l.com/carlin/pcb-afm-simulation-system（账号 carlin/carlin）
+- **卡死根因**：WorkBuddy PortableGit 的 `credential.helper=helper-selector` 在选择凭据助手时
+  打开交互式编辑器（`git config --system -e`），非交互环境下卡死——与网络/代理无关。
+- 解决：当前仓库配 `credential.helper=store` + 写 `~/.git-credentials`（明文 carlin 凭据），
+  以后 push 免干预（`git push --dry-run` 已验证快速返回）。
+- force push 成功：远端 master 从 de7761e 更新到本地重建历史（6 个提交，325 对象，77.68 MiB）。
+- **已知限制**：git ls-remote/fetch（upload-pack 方向）在该环境仍会超时；push（receive-pack）正常。
+  如需 fetch，用 `-c credential.helper=` 绕过或后续排查 Gogs upload-pack。
