FLX-2111: a --committed-slice names an expose this run does not emit

Family: plan/replay binding (the 2000 band)

Each --committed-slice EXPOSE_ID=file://... is looked up by expose id against the run's own receipt. An id no emit of the run carries -- a typo, or a slice meant for a different bundle -- would otherwise be silently discarded and the emit it was meant for reported as having no slice at all, so the caller is told to supply an argument they did supply. The refusal names the unknown ids and the ones this run does emit.
