feat: re-implement module concatenate

[stormslowly]

close #1231
improve #1165

inner 和 root transform 合并到 concatenate transform 中， concatenate transform 中 使用 var_link 的方式将 import/export 的符号 link 到原始的符号, 以保证 import/export reference 的性质。

import  {x as bar} from "inner"
console.log(bar)

转换成

console.log(x)

import { y as foo} from "ext"
console.log(foo)

转换成

import { y as foo} from "ext"
console.log(ext_namespace.y)

兔子跳跃在代码中，
模块合并犹如魔法般，
导出与引入舞起优美舞蹈，
代码重构如清风拂面，
改变注定代码更耀眼。

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger an incremental review. This is useful when automatic reviews are disabled for the repository.
