Critical: - build script now copies launcher menu + china guide (was missing!) - Windows PATH: handle fresh accounts + warn on 1024 char limit - Windows .bat: remove old .env keys before adding new (no duplicates) Important: - Menu error message: fix range 0-14 → 0-16 - API key input: use read -s to hide plaintext - macOS install: default to .zshrc (not .bash_profile) - Website table: fix column mismatch (td → span inside td)
