ci: test local pip install

[chaimleib]

• Fixed:
  • Build system includes sortedcontainers dependency in the wheel again, fixes Wheel for version 3.2.0 is broken #149
• Maintainers:
  • Local testing happens inside virtual environments,
    instead of in the system-installed Python environment.
  • Add uv-dynamic-versioning.
    This generates automatic version numbers for test.pypi.org,
    based on the distance from the last tag version.
  • CI tests "pip install ."
  • Updated Makefile
  • Updated HACKING.md
