add cursor rules to use uv and makefile

[mewwts]

Note

Add Cursor development guide documenting uv-based package management and Makefile-driven workflows.

• Docs:
  • Add /.cursor/development.md outlining development workflow.
    • Mandates uv for Python package management with key commands.
    • Standardizes using Makefile targets for install, formatting, linting, typing, testing, and cleanup.
    • Lists prohibited direct tool usage (pip install, pytest, ruff, mypy).
    • Notes project structure and reliance on uv.lock and pyproject.toml.

Usually, I prefer to keep local/personal settings out of the project. However, I'm keen to try this out.
