Subject: [PATCH] build: pin minimum Python to 3.13 in pyproject.toml

README.md and requirements-dev.txt already document that the test
harness needs Python 3.13+ (pytest-homeassistant-custom-component
doesn't resolve below it), but only in prose. Add requires-python so
pip fails fast with a clear message on an older interpreter instead of
a wall of "Requires-Python >=3.13" version-list noise.
