The previous implementation allocated a temporary Vector and multiple Strings just to format the context map. This commit switches to a streaming approach using `write!`, which writes directly to the formatter without heap allocations. No functional changes.

There was a problem hiding this comment.
Look reasonable. Would you add a test to guard the output stay the same?
That is, add a (snapshot) test assert the output format (error with context) so that further refactoring can be easilier reviewed.
Introduces unit tests to verify the correctness of the `Display` implementation for the `Error` struct. The new tests cover: 1. Basic error messages without context. 2. Complex messages with multiple context items. Suggested-by: @tisonkun Signed-off-by: Cheng-Yang Chou <yphbchou0911@gmail.com>
