- PR #127863: fix(tools): refuse shared-tmp socket dirs we do not own

These items address a security issue where the SSH ControlPath directory was being created in /tmp with overly permissive world-writable permissions. The fixes enforce 0700 mode on directory creation and add a check to refuse shared temp socket directories not owned by the current user.
