Subject: [PATCH] Require Python 3.14+

Aligns with google3, which switched its default interpreter to 3.14 on 2026-08-03 (go/py314-upgrade), and with Mobly's practice of tracking that floor.

* `pyproject.toml`: `requires-python = ">=3.14"`.
* README: update the stated minimum.
* CI: test matrix is now 3.14 only; the pyink format check moves to a single `lint` job instead of running in every matrix cell.

No code changes; the release notes for the next release should call out the new minimum.
