[CHORE](ci) Test dep floors via lowest-direct matrix

The check-python-code workflow now runs across the supported Python
minor versions (3.10-3.14), and adds a lowest-direct cell that re-
resolves every direct dependency to its declared floor before running
make check. Failures in that cell mean a declared minimum is wrong --
either the code uses a feature newer than the floor admits, or the
pin needs to be raised.

Setting UV_RESOLUTION=lowest-direct causes the existing make uv-sync
to re-resolve from the lockfile rather than follow it, so no separate
lock or constraints file is needed.

The declared floors lie about the actual minimums in several places.
Bump them to what the code requires today:

- pydantic >= 2.12: optionality.py imports
  pydantic.experimental.missing_sentinel, which only exists in 2.12+.
  feature.py imports ModelWrapValidatorHandler at the top level
  (re-exported in 2.10.4) and Tag (added in 2.5).
- ruff >= 0.13: 0.12.x still fires the deprecated UP038 rule under
  select = ["UP"], which the workspace config selects.
- deepdiff >= 8.6: first version shipping a py.typed marker, without
  which mypy errors on import-untyped.

Per-package dev deps that were unpinned (ruff, mypy, pytest in
overture-schema-cli and overture-schema-system; pyyaml, deepdiff in
overture-schema) now match the workspace dev-group floors. uv warns
about unpinned direct deps under lowest-direct resolution; pinning
silences the warnings and makes the floor explicit.
