Subject: [PATCH] build: require Python 3.10 for the prqlc Python package

Python 3.9 is end-of-life and untested here (noxfile.py runs 3.10 and
3.12), and the stale `requires-python = ">=3.9"` claim has broken
Dependabot's uv updater for this binding every day since 2026-08-07:
Dependabot pins a candidate exactly, and pytest==9.1.1 requires 3.10+,
so the python_full_version == '3.9.*' resolution fork is unsatisfiable
and the whole job aborts.

Regenerate uv.lock, which also picks up the pytest bump the blocked
updater would have proposed.

 **Integrations**:
 
+- The `prqlc` Python package now declares `requires-python = ">=3.10"`. Python
+  3.9 reached end-of-life in October 2025 and was never exercised by the test
+  matrix, which runs 3.10 and 3.12. The stale `>=3.9` claim also blocked every
+  Dependabot update to the binding's Python dependencies, because a pinned
+  candidate that itself requires 3.10+ leaves the 3.9 resolution fork
+  unsatisfiable. Users still on 3.9 continue to resolve the last release that
+  declared support for it. (@prql-bot, #6225)
