v1.8.3 - fix crash in SystemExtensionScanner path extraction

The closed range `pathStart.lowerBound...pathEnd.upperBound` traps when
`.systemextension` lands at the end of a line (upperBound == endIndex)
or appears before the first `/`. Use a half-open range and guard the
ordering. Reproduced by an external user on macOS 26.4.1.
