build: add support for Python 3.14

[AlessandroPomponio]

Summary

Adds support for Python 3.14 to the ado project by updating version constraints and conditionally excluding incompatible plugins.

Closes #873

Changes Made

• Updated requires-python constraint from >=3.10,<3.14 to >=3.10,<3.15
• Added Python 3.14 classifier to project metadata
• Conditionally excluded incompatible plugins for Python 3.14:
  • ado-autoconf (fastai requires spacy with wheels only on GitHub)
  • ado-trim (Autogluon pyarrow compatibility issues)
  • profile-space (fg-data-profiling requires numba<0.63)
• Updated tox test matrix to include Python 3.14 (py314)
• Added Python version markers to test dependencies and tox configuration
• Excluded incompatible workspace members from Python 3.14 builds
• Updated test fixtures and test files to handle Python 3.14 compatibility

Testing

• Added Python 3.14 to tox test environments (py3{10,11,12,13,14})
• Configured conditional test execution to skip incompatible plugin tests on Python 3.14:
  • SFTTrainer tests (skipped on 3.13 and 3.14)
  • Autoconf plugin tests (skipped on 3.14)
  • TRIM operator tests (skipped on 3.14)
• Core test suite runs on all Python versions including 3.14
• Updated lock files (uv.lock) to reflect new dependencies

Additional Notes

This change maintains backward compatibility with Python 3.10-3.13 while enabling Python 3.14 support. Plugins that are incompatible with Python 3.14 are conditionally excluded using environment markers, allowing the core functionality to work on the new Python version while gracefully handling plugin incompatibilities.
