[Bug] Environment variables in bash commands trigger unnecessary user prompts

Bug Description
Sometimes bash commands have env vars preceeding the command. This causes claude to prompt the user if its okay to run the command, even if the command has already been approved previously.

Example: DOCKER_BUILDKIT=1 docker build .

When checking if we need to prompt the user for permission to run this command, we should first prune the env vars and get to the actual command
