ESP-IDF include 头文件 C++ IntelliSense 飘红解决

1. 打开命令面板，执行 idf.py reconfigure
2. 打开命令面板，执行 ESP-IDF: Add VS Code Configuration Folder，或者扩展面板中执行 Add .vscode subdirectory files
3. 仍然飘红，在 .vscode/c_cpp_properties.json 的配置中添加 "compileCommands": "${workspaceFolder}/build/compile_commands.json"
   形如：

{
  "configurations": [
    {
      "name": "Linux",
      "includePath": [
        "${workspaceFolder}/**"
      ],
      "defines": [],
      "cStandard": "c17",
      "cppStandard": "gnu++17",
      "intelliSenseMode": "linux-gcc-x64",
      "compilerPath": "/var/home/chen/.espressif/tools/xtensa-esp-elf/esp-13.2.0_20250707/xtensa-esp-elf/bin/xtensa-esp32-elf-gcc",
      "compileCommands": "${workspaceFolder}/build/compile_commands.json"
    }
  ],
  "version": 4
}
