feat(trie): 添加字典树数据结构实现

- 实现了Node和Trie类的基本结构
- 添加了insert方法用于插入单词
- 添加了search方法用于搜索完整单词
- 添加了startsWith方法用于前缀匹配
- 实现了字典树的完整功能逻辑

fix(compiler): 修复变量声明和数组访问的代码生成问题

- 为int、float、bool类型变量添加默认初始化值0
- 修复数组维度解析中的括号处理逻辑
- 解决赋值表达式上下文中的数组访问问题

example(prime): 添加素数计算性能测试示例

- 实现了NthPrime函数计算第n个素数
- 添加了时间测量功能
- 提供了30000个素数计算的性能测试用例
