'ccs bar install' previously ended with two manual steps: clearing the
Gatekeeper quarantine by hand and running 'ccs bar' separately.
Install now detects an existing installation and says so before
reinstalling, clears the quarantine attribute itself via execFile with
a graceful fallback to the printed hint when xattr fails, and ends with
a TTY-aware 'Launch CCS Bar now?' prompt (default yes) that hands off
to the existing launch flow. --launch forces the handoff and
--no-launch suppresses it for scripted installs; non-TTY runs skip the
prompt and print the manual command instead.
Closes#1504
Add a 'Get CCS Bar' promo banner + card to the dashboard (mirroring the
OpenRouter promo pattern + design system) so users discover the macOS menu-bar
app, with a macOS-aware install CTA. Add a user-facing docs/ccs-bar.md covering
what it is, install via 'ccs bar install', launch, what it shows, uninstall,
and the loopback requirement -- closing the docs-sync gap for the new ccs bar
command.
