0.21.0 (2026-08-07)

⚠ BREAKING CHANGES

• workos install now stops in a project that already has an AuthKit SDK installed. Pass --force to continue.
• the automatic setup offer after login/install now defaults to No; pressing Enter at the prompt declines instead of installing. Non-interactive contexts remain untouched (nothing is ever installed without --yes).

Features

• stop the installer from clobbering configured AuthKit projects (#205) (04896f6)
