Pull request overview
This PR switches Poetry from pipx backend to a new vfox backend, implementing better Poetry integration through a custom vfox plugin with virtualenv auto-activation support. It also fixes test issues related to Poetry deprecation warnings and removes references to the discontinued zprint plugin.
- Adds vfox backend as primary option for Poetry with pipx as fallback
- Updates test_plugin_install to use tiny instead of removed zprint plugin
- Fixes test_poetry_slow to handle Poetry 1.7.1 deprecation warnings
