feat: add qvariantToCmd helper function

[18202781743]

1. Added new helper function qvariantToCmd to properly format QVariant
   values for command line usage
2. Modified context menu handling to use the new helper when copying
   values
3. Ensures boolean and numeric values are copied without quotes while
   strings remain quoted
4. Fixes issue where raw QVariant values could cause syntax errors in
   command usage

feat: 添加 qvariantToCmd 辅助函数

1. 新增 qvariantToCmd 辅助函数，用于将 QVariant 值格式化为适合命令行使用
   的格式
2. 修改上下文菜单处理逻辑，使用新辅助函数复制值
3. 确保布尔值和数值不加引号复制，而字符串保持引号包裹
4. 修复原始 QVariant 值可能导致命令语法错误的问题

Summary by Sourcery

Introduce qvariantToCmd helper to format QVariant values for command-line use and update context menu actions to use it, ensuring correct quoting behavior and preventing syntax errors.

New Features:

• Add qvariantToCmd helper function for formatting QVariant values as command arguments.

Bug Fixes:

• Fix syntax errors in command usage caused by raw QVariant values.

Enhancements:

• Use qvariantToCmd in context menu copy actions to format values correctly based on type (booleans and numbers unquoted, strings quoted).

关键摘要:

• qvariantToCmd 函数中使用了 QJsonValue::fromVariant，但未处理 QVariant 为 QMetaType::User 类型的情况，可能会导致未预期的行为。
• qvariantToCmd 函数中对于 jsonValue.isBool() 和 jsonValue.isDouble() 的判断，可能需要考虑其他类型的 QVariant，例如 QVariant::String。
• Content::onCustomContextMenuRequested 函数中，value 变量被直接转换为 const QString &，这可能会导致潜在的内存泄漏，因为 value 是一个局部变量。
• Content::onCustomContextMenuRequested 函数中，copyAction 的 triggered 信号连接使用了 lambda 表达式，但没有使用 std::move 来避免不必要的拷贝。

是否建议立即修改:
是

Reviewer's Guide

Introduces a "qvariantToCmd" helper to format QVariant values for shell commands—unquoted for booleans and numbers, quoted for strings—and updates context-menu copy actions to use it, thereby preventing syntax errors when copying raw QVariant values.
