描述

The problem

While working on #5378, I've noticed few TODOs about the need to add destination to error message, when copying or symlinking fails. It seems very useful for me.

Possible solution

  1. Add new optional field to error
  2. Update code for coversion to diagnostic
  3. Update all usages to include it

If it's desired feature, I will work on this!

研究方向
Examine the linked issue #5378 for the original context and any TODOs in the codebase regarding error messages for copying/linking. Locate the error type definitions (likely in a module like `error.rs`) and the conversion to diagnostic function. Review existing usages of these errors to understand the current pattern. The changes involve adding an optional destination field, updating the diagnostic conversion, and ensuring all relevant call sites include the destination. Pay attention to maintainer feedback in the issue comments for any additional guidance.
