Shared browser, separate tab groups: when an agent drives the user's real Chrome
via ab-connect, every tab it opens lands in a Chrome tab group named after its
--session (stable color per name). Each agent's tabs stay visually separated from
other agents' and from the user's own (ungrouped) tabs. Visibility is NOT
restricted — all agents still see all tabs (per design).
- CreateTargetParams gains an optional non-CDP `agentGroup` hint (skip-if-none),
so a strict real-Chrome endpoint never receives it
- BrowserManager.agent_group(): Some(session) only when ws_url == the live
ab-connect relay URL (never on launched/direct CDP); DAEMON_SESSION set at
daemon start supplies the name; emitted at all createTarget sites (transient
storage target stays None)
- ab-connect: +tabGroups permission; Target.createTarget reads agentGroup and
groups the new tab (create/reuse by title, deterministic color), best-effort
- extension 0.3.0 -> 0.4.0; re-signed crx + zip (id unchanged)
Needs the v0.4.0 extension reloaded + a build with this change to take effect.
