Add remote (SSH) workspaces (#739)

* Add remote (SSH) workspaces

Workspaces gain a type (local/ssh) + typeData. When an SSH workspace is
active, terminals, git, worktrees, the project picker, file ops, and the
muxy.exec/files/git extension APIs all execute on the remote host via the
system ssh binary — routed at a single execution seam (WorkspaceContext).

Closes #438

Fix extension host socket connect race (#680)

* Retry extension host socket connection to fix startup race

The host connected once and died on a transient socket-not-ready error, requiring an app restart. Retry the connect (~5s) so it self-heals on startup and reload.
