Release version 1.3.2

[sirosen]

Changelog

This is the changelog from v1.3.2 , verbatim, at time of writing.

• Add support for Python 3.14 and 3.15
• Remove support for Python 3.8
• Correct the type of the dependency_groups parameter to resolve(),
  resolve_all(), and DependencyGroupsResolver().
• Raise a clear TypeError when an include-group value is not a string
  (was a cryptic TypeError from name normalization), and accept any
  Mapping for include items, not only dict.
• Fix a bug in which pip-install-dependency-groups failed when the
  resolved groups were empty. It now prints Nothing to install and exits
  normally.
• dependency-groups --list now respects the -o/--output option.

Minor vs Patch

I decided on a patch release, as there are no new features. Only fixes and Python support updates.

Aside: Process

@henryiii I gave it a short rest (since the last change) before prepping this, and then went over the release process for this repo to push this out.

I noticed some process/meta things:

• there isn't a documented process at all (!), not even a super short 3-line RELEASING.md -- I plan to add one, just so the mechanism is documented
• the last release (1.3.1) was done in the style of a solo maintainer; I'd like to switch to using release PRs like this one
• the current publishing flow is
  • tag triggers Test PyPI workflow
  • GitHub release triggers PyPI workflow

That setup (tag and release triggers) is the way I do things for most of my independent projects, but I can adapt if there are changes you think we/I should make.

After approval, I'll merge, tag, and create the release. :)
