The pre-message printed by setup/register-claude-token.sh used to
say "A browser window will open for you to sign in with your
Claude account." Accurate on a laptop or desktop, but a lie on
headless devices (Pi, SSH'd-into Linux server, CI) where the
browser auto-open never lands and the user actually has to copy
the URL `claude setup-token` prints to another device.
Add a small bash isHeadless check (mirrors `isHeadless()` in
setup/platform.ts: Linux without DISPLAY / WAYLAND_DISPLAY) and
swap the heredoc accordingly:
- Headless: "A sign-in link will appear for you to sign in with
your Claude account. When you finish, we'll save the token
to your OneCLI vault automatically."
- GUI: existing "A browser window will open…" copy, unchanged.
The trailing "Press Enter to continue, or edit the command first."
line and the actual `claude setup-token` invocation are unchanged
— only the leading sentence flips.
