…arsing Guard against null pointers in log_syntax_error. Avoid reading/writing at end by using bounded line scanning. Replace temporary in-place buffer mutation with length-limited logging (%.*s). Prevent potential SIGSEGV/SIGABRT when malformed include syntax reaches EOF.

Pull request overview
This PR hardens malformed include(...) parsing error handling in the JST parser to avoid out-of-bounds access and crashes when the parser reaches EOF or encounters invalid syntax.
Changes:
- Adds null-pointer guarding in
log_syntax_error. - Reworks line scanning to be bounded by
end(avoiding reads/writes at EOF). - Switches logging from in-place buffer mutation to precision-limited
%.*sprinting.
