Performance: Optimize parseLine regex #70
Conversation
Moves the regex definition outside of the `parseLine` function to avoid recompilation on every call. Ensures `lastIndex` is reset to 0 to handle global regex state correctly. Benchmark showed ~5% improvement (from ~701ms to ~665ms for 1M iterations).
