- PR #138978: fix(ssh): budget the full ControlMaster listener path for every root

The three members concern where the SSH backend places its ControlMaster Unix socket directory: one reports a "path too long for Unix domain socket" error for named profiles and notes ssh.py does not use socket_safe_tmpdir, one proposes a short per-user root, and one proposes refusing shared-tmp socket dirs not owned by the user. Their status and outcomes are not established by the titles.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.50`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
