Description

Makes DicoGIS publishable on PyPI, so that pip install dicogis / pipx install dicogis (already documented in the installation guide) can work.

• build: require setuptools>=77. license = "Apache-2.0" is a PEP 639 SPDX expression, which older setuptools reject (reproduced with setuptools 76.1 and --no-isolation).
• build: drop the unused setuptools-scm build requirement. It isn't configured, but as a build-time file finder it made the sdist embed every git-tracked file (11 MB instead of 0.5 MB) and the wheel ship the .ts translation sources, which package-data deliberately leaves out.
• test: new tests/test_packaging.py checking that every .ui/.qm file is covered by [tool.setuptools.package-data], that no pattern matches nothing, and that the setuptools floor supports the SPDX license.
• ci: the build and release workflow (builder_releaser.yml) now also handles the Python package, as QDT does. A build-python-package job builds the sdist and the wheel, runs twine check --strict and, on a tag, refuses a tag that doesn't match the package version (compared as PEP 440 versions). The release job attaches them to the GitHub release, and a release-pypi job publishes them from the pypi environment with Trusted Publishing (no API token). On pull requests touching pyproject.toml or MANIFEST.in, the package is only built and checked.
• docs: docs/development/releasing.md describes the automated publication and the one-time setup, and the manual fallback is fixed. CLAUDE.md notes the packaging rules.

To do before the first release

1. On PyPI, add a pending publisher: project dicogis, owner Guts, repository DicoGIS, workflow builder_releaser.yml, environment pypi.
2. On GitHub, create the pypi environment (optionally with required reviewers).

Verification

• Built the sdist and the wheel with python -m build: twine check --strict passes and the wheel contains the .ui, .qm, locale and bin files.
• Ran the tag check of the workflow against the built wheel: matching tag passes, mismatching and non-version tags fail.
• The new tests fail when the setuptools floor, a package-data pattern or a .ui location is broken on purpose.
• pre-commit hooks pass on the changed files; tests.test_about and tests.test_packaging pass.
• Not verified: the workflow on GitHub Actions, the full pytest suite (needs fixtures and PostGIS), and the availability of the dicogis name on PyPI (pip index versions found nothing, to be confirmed on pypi.org).
