解决coc-clangd代码片段补全禁用配置不生效的问题

你当前的问题出在配置项位置错误：clangd.disableSnippetCompletion是coc-clangd插件的专属配置，不能嵌套在languageserver.coc-clangd这个语言服务器基础配置块里，必须放在配置文件顶层。

修正后的配置

将该配置移到顶层，修改后的coc-settings.json如下：

{
    "languageserver": {
      "coc-clangd": {
        "command": "clangd",
        "rootPatterns": ["compile_flags.txt", "compile_commands.json"],
        "filetypes": ["c", "cc", "cpp", "c++", "objc", "objcpp"],
        "clangd.arguments": ["--enable-cxx20"]
      }
    },
    "clangd.disableSnippetCompletion": true,
    "rust-analyzer.enable": true,
    "rust-analyzer.inlayHints.enable": true,
    "rust-analyzer.cargo.buildScripts.enable": false,
    "pyright-enable": true,
    "suggest.enablePreselect": false,
    "suggest.noselect": true,
    "snippets.priority": 10
}
