fix: support Python 3.14 development

[korowant]

Summary

• refresh the locked Pydantic stack to versions that publish CPython 3.14 wheels
• advertise Python 3.14 in the package classifiers
• add Python 3.14 to the unit-test CI matrix

Problem

The project declares requires-python = ">=3.12", but a fresh uv sync --python 3.14 --group dev fails while building the locked pydantic-core==2.33.2. Its PyO3 version only supports Python through 3.13.

Updating the lock to pydantic==2.13.4 and pydantic-core==2.46.4 uses the published CPython 3.14 wheels instead of attempting the incompatible source build.

Impact

Contributors using Python 3.14 can install the development environment and run the SDK unit tests. CI now protects that compatibility alongside Python 3.12 and 3.13.

Validation

• uv lock --check
• Python 3.12: 76 passed, 17 deselected
• Python 3.13: 76 passed, 17 deselected
• Python 3.14: 76 passed, 17 deselected
• uv build
