[Copilot]

Adds CI testing for Python 3.10-3.13 and declares version support in project metadata per requirements.

Changes

Workflow (.github/workflows/multi-python-test.yml)

• Matrix strategy tests all four Python versions in parallel
• Uses UV for dependency management, 15min timeout for uv sync
• fail-fast: false ensures all versions tested
• Explicit permissions: contents: read for least-privilege security

Metadata (pyproject.toml)

• Added classifiers for Python 3.10, 3.11, 3.12, 3.13
• Included license (AGPL v3) and OS (OS Independent) classifiers
• Existing requires-python = ">=3.10" unchanged

The workflow runs on push to master, PRs, and manual dispatch. Excludes documentation changes.
