dataEffectLiteralString asked the literal owner for an exact value, and
when a template recovered with an invalid escape had no cooked value it
fell back to the raw spelling. Child-process commands, request endpoints
and event names then became resolved values that are not JavaScript
strings.
Use only the owner's cooked value; a template without one stays dynamic.
