ci: add explicit venv cleanup before setup in all workflows to prevent cache corruption

Added `rm -rf venv` (and `venv-build` where applicable) before venv setup in all CI workflows to ensure clean installations and prevent cache corruption issues. Removed redundant venv corruption detection and rebuild logic from package-tests.yml since explicit cleanup makes it unnecessary.
