* feat(switcher): say Offline in words and dim the avatar; drop the link dot for a reachable workspace
The normal case carries nothing extra. An offline machine's row reads
"Offline" under the tab count, where Open and This window go, and its
avatar is dimmed. A dot stays only for states that want attention:
connecting, reconnecting, failed, or taken over by another client.
* fix(tabs): ⌘T on an SSH tab dials the same host and files the tab under it
A new tab from an SSH pane used to open a local shell in the default
directory, which landed in Ungrouped instead of under the host the user
was on. A native SSH pane now dials again with its spec, as ⌘D already
did; a shell that ssh'd onward from a local prompt gets a local tab that
types the same ssh command at its first prompt. Either way the tab is
seeded into the host's auto group before its pane reports in.
