[SC-16431] Limit build contents to reduce PyPI package size

[juanmleng]

Pull Request Description

What and why?

Restricted the Hatch build outputs so published artifacts only include the validmind package and required release metadata. This reduces the source distribution from over PyPI’s 100 MB limit to about 20 MB, preventing upload failures, and removes a stale console-script reference plus outdated docs for a non-existent test-generation script.

How to test

Run uv build and confirm the generated dist/*.tar.gz and dist/*.whl files are created successfully. Verify the source distribution is below PyPI’s 100 MB limit and does not include repo-only directories such as notebooks/, docs/, .github/, scripts/, or the top-level tests/.

What needs special review?

PR Summary

This PR introduces several changes that affect the packaging configuration and the test creation workflow:

• The version numbers have been updated from 2.13.3 to 2.13.4 in various project files (pyproject.toml, DESCRIPTION, uv.lock, version.py). (Note: Version bumps are considered trivial and are not the focus of this summary.)

• A new packaging configuration has been added using Hatch. The PR defines explicit sdist and wheel targets with specified inclusion and exclusion rules. This ensures that only the necessary files are packaged, helping to maintain a clean distribution.

• The project’s test creation mechanism has been modified. The console script registration for generating new tests (vm-create-new-test) has been removed from pyproject.toml, and the corresponding documentation in scripts/README.md has been updated. Users are now instructed to manually create new tests by adding files to the appropriate directory and following the established naming and structure patterns.

Test Suggestions

• Test that the sdist and wheel packages include only the intended files and correctly exclude the specified directories and patterns.
• Verify that the manual test creation process works by creating a sample test file in the validmind/tests/ directory and ensuring it is recognized correctly.
• Confirm that the removed test generation script is no longer available as a console command and that any dependency on it has been properly handled.
• Check that the version information in built and deployed packages reflects the updated version (2.13.4).
