- #46788: fix: get_running_pid() skips PID check when virtiofs unlinks lock file behind gateway's FD

These issues and fixes concern cases where the gateway's PID file or lock file is absent or deleted during restarts and handoffs, causing PID checks to be skipped or CLI communication to break. The changes adjust fallback behavior so the PID check still runs when the lock file is missing.

## 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evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.39`: 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.
