[Feature Request] Add trusted folder allowlist to skip permission prompts on session start

Bug Description
I want to be able to mark a folder as trusted for Claude Code so it won't prompt me to trust the folder in the beginning of a session. This is similar to the permissions model of direnv, where I can mark a folder as trusted with direnv allow <PATH> before entering it, so it won't prompt me to trust it when I change directory into it. I'd also like to be able to pre-trust a certain list of tools in that case so that I won't need to tell it all over again to trust gh, git, etc.
