_presence() cleared is_cli/is_gateway/is_ask for single-query sessions but
not for cron, so a cron worker that inherited HERMES_INTERACTIVE /
HERMES_EXEC_ASK from its launching gateway resolved as an interactive CLI
and blocked on an approval card nobody could answer (measured: 31
pending_approval hangs/hour, 6 stranded claims — #110932).
Mirror the single-query clearing for _is_cron_approval_context(), matching
the cron exclusion already inside _is_gateway_approval_context(). Layer 1
(#110942) strips the vars at the launch path; this makes the gate robust
to any other leak route.
