refactor: remove duplicate browser prompt instructions (#35)

Remove browser instruction text repeated across tool descriptions, parameter schemas, tool
guidelines and the global browser prompt. Tool names, schemas, handlers and concurrency are
unchanged; shared recovery and ownership guidance is now available before and after the browser
connects, and the prompt names which tools are serialized versus observations.
