feat(system): chore(lint): ruff auto-fix sweep — 303 errors across 178 files (F401 unused imports + F541 f-string placeholders + F811 redefined); restored report_error re-export + added logger call in errors.py (#333)

* feat(system): fix(windows-ci): combine pip bootstrap fix + venv activation in Verify step

Combines both fixes needed to get windows-test.yml actually passing:

1. setup.sh: stop swallowing ensurepip errors (quiet + 2>/dev/null + || true was
   hiding real failures — pip was silently not installed). Add get-pip.py fallback
   and hard pip verification.

2. windows-test.yml: add 'source .venv/Scripts/activate' to Verify step. Each CI
   step gets a fresh shell — setup.sh's venv activation doesn't carry over, so
   drone wasn't on PATH in the subsequent step.

Together, these should take Windows CI from the 'silent failure every run since
creation' state to actually green. Supersedes PRs #330 and #331 which had the
fixes on separate branches (neither green alone).
