When parsing malformed input with many syntax errors (e.g., via eval
with a long garbage string), the parser would continue until the end
of input, causing long execution times.
Add an early termination check in the lexer that returns EOF once
the error count exceeds 10 (same as error_buffer size). This prevents
DoS from inputs like eval("garbage" * 1000).
