ci: narrow Python support to 3.12-3.14 (#356)

ComfyUI recommends 3.13, names 3.12 as the fallback and 3.14 as working
(its README); PromptManager supports exactly those. requires-python is
>=3.12, the test matrix and the required checks drop 3.11, and bandit
runs on 3.12.

-CI runs the suite on Linux, Windows and macOS for Python 3.11 to 3.14 with an 85% coverage gate. `python -m unittest discover -s tests` still works; see `TESTING.md` ("Time limits and hangs") for the watchdog. Tests that delete a database file first check that nothing in the process still holds it open (`tests/open_handles.py`), so a connection leak fails on Linux the way it would on Windows.
