Pull Request Overview
This PR adds a version constraint to prevent pip from upgrading to version 25.x, which is incompatible with the currently-used pip-tools 7.5.1. The constraint addresses an AttributeError related to 'use_pep517' that occurs when pip 25.x is used with pip-tools 7.5.1.
- Adds a pip version constraint (
pip<25.0) to the constraints file - Includes explanatory comments documenting the incompatibility issue and the rationale for the constraint

There needs to be an issue created as well for this.
Which should be linked here as well.
And the issue needs reasoning as to why this is pinned.

Summary
There is a breakage currently in pip-tools that failed several / many / all? python requirement upgrades: jazzband/pip-tools#2252 The temporary solution may be to pin pip to the last minor version, but it does look like a fix in on the way.
Findings
The error is stemming from the removal of the legacy setup.py bdist_wheel support in pypa/pip#6334 which removes the optional flag --use-pip517 that had been added for the support of deprecated legacy functionality.
Since all versions of pip-tools utilize this flag for the pip-compile command, the new version pip==25.3 is now breaking with all the versions of pip-tools hence the need to pin pip as a solution for this until pip-tools provide a workaround for this issue in their next release.
