canonicalErrorKind
Maps this core parse/relative failure to its canonical, language-neutral errorKind string.
This is the single place the Kotlin KPointerException subtypes are translated into the language-neutral vocabulary that the shared conformance fixtures assert against. RelativeMalformedSyntax intentionally collapses every syntactic relative-pointer failure into one kind (relative-malformed-syntax).
Return
The canonical errorKind string for this exception.
Receiver
The core exception raised while parsing a pointer string or applying a relative pointer.
