Huashu Script Polish

This takes your video script drafts and makes them sound like actual human speech instead of written text. It runs three passes: content accuracy, conversational rewrite (the main event), and presentation notes. The second pass is where it earns its keep, swapping out stiff phrases like "接下来我们将进行" for natural ones like "我们来", adding filler words that real people use, and breaking up long sentences so you don't stumble when recording. It's tuned for Chinese YouTube-style content at 150-180 characters per minute. If your scripts read fine but sound robotic when you actually say them out loud, this is the fix.
