​Introducing BotID, invisible bot filtering for critical routes

Introduces BotID, a new layer of protection on Vercel designed to stop sophisticated bots that mimic human behavior before they reach critical backend routes. BotID injects obfuscated, mutating JavaScript code to collect signals distinguishing humans from bots, feeding into a global ML network. It offers a simple server-side check (`checkBotId`) with no configuration required. Deep Analysis mode, powered by Kasada, provides enhanced protection for high-value applications.
