test(producer): treat an all-literal probe argv as taking no input

Browse Source 
CI runs the PR merged with main, so it saw a caller my branch predated:
`spawnSync("ffprobe", ["-version"])` in engine/src/utils/ffprobe.test.ts. That
is a capability check with no runtime path, so there is nothing to terminate,
but the unclassified guard flagged it as a caller it could not parse.

An argv whose entries are all string literals carries no input by
construction. Those are dropped before the check; an argv with a bare
identifier still has to be understood, verified by adding one and watching the
guard fail.
