Hello Replacer

Does exactly what it says: finds every instance of "hello" in your codebase and replaces it with "fuckk" while preserving case. It greps through files, skips binaries and lock files, and stays out of node_modules and .git directories. Honestly, this is pretty niche. You'd use it if you're bulk-editing greetings for some reason, maybe as part of a joke refactor or testing find-and-replace logic at scale. It's well-structured with proper case handling (hello becomes fuckk, Hello becomes Fuckk, HELLO becomes FUCKK) and reports what it changed. Practical implementation of a very specific, somewhat silly task.
