Summary

This PR fully drops support for Python 3.9. Specifically we:

  • Raise minimum supported Python version from 3.9 to 3.10
  • Remove Python 3.9 package metadata/classifiers
  • Stop building and publishing cp39/pp39 wheels
  • Replace the current runtime deprecation warning with a hard failure for Python < 3.10
  • Update user-facing docs/release notes to state that 0.15.x is the last series supporting Python 3.9

Closes #700
