feat: modernize repo to use uv, pyproject.toml, and semantic-release

[farhan]

Important

PR implemented with the assistance of Claude Code, human-reviewed and improved before pushing to code review.

Summary

Modernize edx-enterprise-data to uv + pyproject.toml (PEP 621/735) + python-semantic-release.

Part of openedx/public-engineering#506.

• Replace setup.py with pyproject.toml (PEP 621 static metadata)
• Switch from pip-compile to uv with PEP 735 dependency groups; commit uv.lock
• Replace pylint/isort/pycodestyle with ruff (check + format); coverage config moved into pyproject.toml
• Update tox.ini to use tox-uv with uv-venv-lock-runner
• Update CI to use astral-sh/setup-uv; SHA-pin all actions; add workflow_call trigger
• Add python-semantic-release + release.yml

Removed

Deleted files: setup.py, CHANGELOG.rst, pylintrc, pylintrc_tweaks, requirements/

Removed Makefile targets:

Target	Reason
coverage	Coverage is now reported via pytest-cov in tox; HTML report generation dropped
isort	Replaced by ruff format (handles import sorting)
piptools-requirements	pip-compile toolchain removed; uv handles dependencies
test-all	Superseded by tox (run directly via uv run tox)
validate	Redundant wrapper around test + quality; tox envlist covers both

Versioning

[Dynamic] setuptools-scm with dynamic = ["version"] — master had a PyPI publish workflow (pypi-publish.yml); python-semantic-release controls the version string at release time via git tags, replacing the old manual workflow.

Testing Notes

This PR has not been manually tested against the repo's own features. Testing relied on CI checks and local agent tooling (make requirements, make lint, make test, python -m build). Repo-owner is encouraged to run the repo's feature tests before merging.

Code reviewer notes:

• Scrutinise the pyproject.toml dependency groups carefully to ensure no test or dev dependency leaked into the [project.dependencies] (production) group, especially given the large number of requirements files that were consolidated.

Re-implement update — new commit 7fcf0e8 fixes three issues found during test-suite review:

1. Constraints config (pyproject.toml): uv_constraints was set to boolean true instead of a TOML array; and constraint-dependencies was empty ([]) even though requirements/constraints.txt existed on master. Fixed: set uv_constraints = ["mysql-connector-python<9.6"] (the Django<5 pin from master was a service-level deployment constraint that conflicts with the test group requiring Django 5.2, so it is excluded), then ran edx_lint write_uv_constraints to populate constraint-dependencies with the common+repo-specific constraints and regenerated uv.lock.

2. Invented fail_under (pyproject.toml): fail_under = 70 was added to [tool.coverage.report] but master had no .coveragerc and no coverage threshold at all. Removed per the "no inventions" rule.

3. PyPI auth mechanism (release.yml): publish_to_pypi was using OIDC (id-token: write) but master's pypi-publish.yml used token auth (password: ${{ secrets.PYPI_UPLOAD_TOKEN }}). Switched to token auth to match master.

4. Added codecov.yml: Minimal header-only file as required by the modernization standard (was missing from earlier commits).
