Modernise build tooling and configuration

[MarkBird]

Transition the project from the old-school setup.py style to the more modern pyproject.toml approach.

Nice modernisation overall 👍 — this is a clean move from setup.py to pyproject.toml, and the CI publishing flow is much more current (using build + PyPI trusted publishing).

I think this is close, with a couple of things worth confirming before merge:

1. requires-python changed to >=3.10

   • This is a significant support-policy change compared to the previous packaging setup (which built on 3.8).
   • If intentional, great — but it would be good to call it out explicitly in release notes/changelog.
   • If not intentional, you may want to keep this aligned with the project’s actual supported Python versions.

2. GitHub Action now uses trusted publishing (pypa/gh-action-pypi-publish)

   • Good upgrade, but this depends on PyPI trusted publisher configuration for the repo/environment.
   • Worth double-checking that this is already configured, otherwise publish jobs will fail at release time.

3. Package data behaviour changed

   • setup.py previously had custom get_package_data(...); the new config only declares package discovery.
   • If there are any non-Python files under log_request_id that should be included in distributions, confirm they’re still being shipped with the new build config.

If those points are intentional/covered, this looks good to merge.

Thanks for the update — the migration itself still looks clean.

I don’t see anything new in the diff that resolves the three non-code confirmations from the previous review, so before merge I’d still like explicit confirmation on:

• requires-python now being >=3.10 (intentional support-policy change, and documented accordingly).
• PyPI trusted publisher setup being configured for this repo (since the workflow now depends on OIDC publish).
• Whether any non-Python files previously included via get_package_data(...) are still included in built artifacts.

Once those are confirmed, this looks good to go.
