Update Python/Django support matrix

[loookashow]

Refreshes the Python/Django support matrix, which had fallen behind the latest stable releases. Independent of the tags/search PRs (#320, #321) — branched off main.

Versions verified against upstream docs (not memory):

• Python 3.14 — stable since 2025-10-07. 3.15 is still a prerelease, so it's not included.
• Django 6.0 (6.0.8) — the latest stable release. 6.1 is only at rc1, so it's not included. Django 6.0 supports Python 3.12, 3.13, 3.14; Django 5.2 added 3.14 support in 5.2.8.

Changes

README — compatibility table:

• New 6.0 column (v for Python 3.12–3.14 only; 6.0 requires 3.12+).
• New 3.14 row (v for Django 5.2 and 6.0 only).
• Requirements line now lists 3.14.

CI (.github/workflows/test.yml):

• functional: Python 3.14 added to the matrix.
• New django-6 job: Django 6.0 on Python 3.12, 3.13 and 3.14.

The django-6 job uses the latest Poetry rather than the pinned 1.4.2 the older Django jobs use — 1.4.2 does not run on Python 3.14. The older jobs keep the pin so they keep working on Python 3.8.

The python = ">=3.8,<3.15" and Django = ">=2.2" constraints already cover 3.14 and 6.0, so pyproject.toml needs no dependency changes. (A Python :: 3.14 trove classifier was intentionally left out — the current toolchain's trove-classifiers doesn't recognize it yet, which would fail poetry build; it can be added once that updates.)

Note: 5.2 + 3.14 is a valid combination but is not tested as its own CI cell, to avoid running the pinned old Poetry on Python 3.14. Both 5.2 and 3.14 are exercised by other jobs.

Seems like adding 3.14 support is not impossible without bumping the pydantic version, which in turn breaks 3.8 compatibility

we should use conditional, let me try.
