Description

Summary

Raise Lightly's minimum supported Python version to 3.8.

Why

Python 3.7 is EOL

Scope

  • packaging metadata/classifiers
  • CI workflow matrices and helper targets
  • docs / Read the Docs references

Acceptance

  • minimum version is 3.8+
  • CI no longer runs 3.7
  • docs and metadata match

Contributor guide

Research direction
Identify all references to Python 3.7 in packaging metadata (setup.cfg/setup.py), CI workflow files (.github/workflows), and documentation, then update them to 3.8.
