[skjson] Detect end-of-input for unbalanced strings
We currently blow through string chars without checking for end-of-input.
Maybe we could avoid this upfront, when we locate the stop char: try to
determine if it's part of an unterminated string, fail immediately if
so. Figuring out if the tail is an unterminated string seems
intractable though (requires arbitrarily deep tail parsing).
That brings us to plan B:
* treat scope-closing tokens (} & ]) as string terminators
(we know end-of-input points to one of these for sure)
* adjust matchString() to check for end-of-input
