Trailing non-json whitespace is not rejected.

Consider a simple input like the number 1 followed by a nonbreaking space: "1\u00A0"

JSON.parse correctly rejects this, but jsonriver v1.0.1 does not. Looks like we are using .trim() which skips a larger variety of space characters, instead of our strict skipPastWhitespace in expectEndOfContent.

This bug was reported over email by someone who says they found it with the assistance of GPT-5 high! Waiting to hear if they want public credit for finding this bug, but I'm quite thankful and impressed!

Thanks to @alexyorke for reporting this! The fix is released in v1.0.2
