fix(process): improve error message for process.cwd() when directory is deleted

[Ankush1oo8]

This PR improves the error message thrown by process.cwd() when the current working directory is deleted. Instead of throwing a new error, it enhances the original error message, making it clearer that the directory was deleted while the process was still inside it.

Changes Made:

• Modified wrappedCwd() to enhance the existing error message for ENOENT: uv_cwd instead of creating a new Error instance.
• Ensured the error message explicitly states the reason and how to resolve it (using process.chdir() to switch directories).

Before (Old Behavior):

When the working directory was deleted, process.cwd() threw a generic error with little context:

Error: ENOENT: no such file or directory, uv_cwd

After (New Behavior):

Now, the error provides a more meaningful message:

Error: Current working directory does not exist - this can happen if the directory was deleted while the process was still inside it. Original error: ENOENT: no such file or directory, uv_cwd
