Description

Add Python 3.15 to the CI test matrix on Linux, Windows, and macOS and to the scheduled dependency-audit matrix on Linux and Windows. Update the corresponding workflow assertions while retaining Python 3.11–3.14 coverage and the existing minimum Python requirement.

Testing

• Tested locally with uv run specify --help
• Ran existing tests with uv sync && uv run pytest
• Tested with a sample project (if applicable)

Ran .venv/bin/python -m pytest tests/test_github_workflows.py tests/test_security_workflow.py -q: 171 passed.

Ran git diff --check: passed.

The full suite, CLI help check, and sample-project checks were not run for this CI matrix-only change. The workflow checks ran locally on Python 3.13; Python 3.15 execution on the configured platforms remains for CI.

🔵 Needs a closer look

The workflow and assertions are reviewable, but Python 3.15 compatibility and dependency resolution across all three hosted operating systems still require confirmation from a human-reviewed CI run.
