Add Python 3.14 support

- Bump requires-python upper bound from <3.14 to <3.15
- Add Python 3.14 classifier
- Add Python 3.14 to CI test matrix
- Add python_version < 3.14 marker for gradio (blocked by pydantic-core)
- Bump actions/checkout v3->v5, actions/setup-python v3->v6, actions/cache v3->v4

Blockers resolved since PR microsoft#1130 was opened:
- datasets/PyArrow: supported since PyArrow 22+
- pyodbc: supported since v5.3.0
- spacy: supported since v3.8.10
- torch: supported since PyTorch 2.10
- semantic-kernel: removed from dependencies

Remaining blocker (optional extra only):
- gradio: blocked by pydantic-core missing 3.14 wheels

Relates to microsoft#1130
