v0.16.1
What's Changed
Fixes GitHub (and other host-bound) logins in the cmux browser lane. __Host--prefixed cookies (such as GitHub's __Host-user_session_same_site) were being delivered with a Domain attribute, which WebKit hard-rejects, so the session cookie silently failed to land and the cmux agent browser stayed logged out despite a successful sync.
cmux now scopes __Host- and host-only cookies by url with no Domain (and forces Secure + Path / for __Host-), matching the CDP and livecdp lanes. Also downgrades insecure SameSite=None cookies to Lax for parity.
