Describe what you have changed in this PR.

Debugging the issue described in #2399 was hard, since PDM didn't provide the very helpful response body
{"message":"Validation failed: Description is too long (maximum is 4000 characters)"}. For some reason, capturing the traffic also didn't work out for me. And resorting to that would require much expertise from users.

This enhancement improves things in a straightforward, but simplistic manner. Ideal would be the ability to log all (structured) API endpoint response data to stdout throughout PDM. That would require more investment and architectural redesign.

The auto-reformatting by my editor seems legit to me. If not, this code base seems to not configure the appropriate line length then.

@sanmai-NL line length is configured in pyproject.toml, for Ruff, at 120 characters. What tool/config is your editor using to auto-format code?

The auto-reformatting by my editor seems legit to me. If not, this code base seems to not configure the appropriate line length then.

Maybe you are not using the proper tool for formatting, we are using ruff-fmt now.

[sanmai-NL]

Off-topic. But my editor still uses Black. It would be ideal if the repository contained an EditorConfig file that matches the Ruff-specific settings.

root = true

[*]
charset = utf-8
continuation_indent_size = 2
end_of_line = lf
indent_size = 2
indent_style = space
insert_final_newline = true
max_line_length = 120
quote_type = single
trim_trailing_whitespace = true
rulers = 100

[*.py]
indent_size = 4
max_line_length = 120
profile = black

Where profile value black would be something like ruff. But I don't know if Ruff supports it yet.

After your review/comment I'll finish the checkbox tasks in the opening post.
