fix(cli): Fix configuration reuse issue in swcDir() by deep clone

[CodeMan62]

• Issue: The swcDir() function in the @swc project was experiencing configuration reuse issues due to shared references in the options object. This led to unintended side effects when compiling different module types (ESM and CommonJS) in the same process.

• Fix: Implemented a deepClone function to ensure complete isolation of configuration objects. This prevents shared references and ensures that modifications to one configuration do not affect others.

• Testing:

  • Created a comprehensive test suite to verify the functionality of the deepClone function. The tests demonstrated that deep cloning maintains object isolation, while shallow cloning does not.
  • Conducted end-to-end tests by simulating the compilation of both ESM and CommonJS modules. Verified that the output file extensions were correct and that the configurations were isolated, confirming the effectiveness of the fix.
