Debian ships venv's ensurepip in a separate python3-venv package. Without it, `python3 -m venv` exits 1, so mason cannot build the venv it installs basedpyright into, and mason-lspconfig reports a failed install on every startup. Add python3-venv to the apt package list, and guard the basedpyright entry in ensure_installed the same way the npm-sourced servers are already guarded, so a machine missing it gets one warning instead of a failed install every time.
