Clean, focused PR that adds Python 3.14 to the test coverage matrix. All changes are consistent and follow existing patterns.

Review Summary

• CI Configuration: Python 3.14 correctly added to Linux, Windows, and macOS test matrices
• pyproject.toml: Classifier and hatch test matrix properly updated
• Pattern Consistency: MacOS continues to test latest version only (now 3.14)

Forward-looking compatibility testing with alpha Python versions is a good practice for early issue detection.
