W3C XPath 1.0 §4.2 (https://www.w3.org/TR/1999/REC-xpath-19991116/#section-String-Functions) defines substring behaviors for negative start indices, zero lengths, and out-of-range bounds. Add tests covering these cases along with empty/non-matching nodes for substring, substring-before, and substring-after.
