Subject: [PATCH] test(worktrees): pin the disconnected-SSH no-teardown
 invariant
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

main's new directSshAuthority gate bails before any refresh when an SSH target
is not connected. That is exactly the #10562 safety rule — "host unreachable"
must never be read as "worktree deleted" — so pin it: a disconnected target
issues no teardown RPC and keeps its renderer state.
