修复自引用检测和类型别名依赖提取

(Optional) More detailed description for this PR(en: English/zh: Chinese).

en:

Fixes two bugs in type dependency extraction:

1. Self-reference detection: Recursive types like type TreeNode = { children: TreeNode[] } incorrectly included themselves in dependencies. Fixed by checking if type reference is within type definition instead of checking if definition is within function.

2. Type alias extraction: Type aliases like type Status = 'normal' | 'abnormal' were not extracted when used in function parameters or return types. Fixed by extracting direct symbol from type nodes before processing nested references.

zh(optional):

修复类型依赖提取中的两个 bug：

1. 自引用检测：递归类型如 type TreeNode = { children: TreeNode[] } 错误地将自身包含在依赖中。通过检查类型引用是否在类型定义内（而非检查定义是否在函数内）修复。

2. 类型别名提取：类型别名如 type Status = 'normal' | 'abnormal' 在函数参数或返回类型中使用时未被提取。通过在处理嵌套引用前先提取类型节点的直接符号修复。

我对 TS-Parser 进行了变更，Regression Test 不通过属于正常现象。

export const PI = 3.14159;
export const E = 2.71828;

export enum Color {
  RED = 'red',
  GREEN = 'green',
  BLUE = 'blue'
}

export type Result<T> = T | Error;

变更后，Result 的 Types 多了 T，这是期望行为吗

Just looked at the test results. Make sense.
