A goal quality gate is a shell command persisted by `/goal gate add` and
later executed with `subprocess.run(shell=True)` at every goal turn
boundary (run_gate), with no approval prompt. On the messaging gateway,
slash access is backward-compatible: with no `allow_admin_from` list
configured (the default), every *allowed* chat user is treated as
unrestricted. So an allowed but non-admin remote sender could add an
arbitrary shell command and get authenticated RCE as the Hermes process
account.
Gate ONLY the shell-creating operation (`gate add`) behind the existing
fail-closed explicit-admin check (`_resume_caller_is_admin`, the same one
that guards cross-origin `/resume`). `gate list` / `remove` / `clear`
stay open so a non-admin can still inspect and recover. CLI/TUI/Desktop
`gate add` is local (the user already has host access) and is unchanged.
Salvaged from #91677 by @unsupportedpastels — narrowed to the single
shell-creating op and reusing the existing admin helper rather than
renaming it. Contributor's regression tests preserved.
