This PR enforces strict JSON parsing for the
null,true, andfalsekeywords.It fixes cases where the parser would accept invalid literals such as
"nope","t123", or"fxxxx"by reading the first token and blindly skipping the remainingbytes using
skipFixedBytes().The change updates
readNull()andreadBoolean()to validate exact keyword bytesand fixes their usage across switch cases to avoid partial or incorrect matches.
