### What? This adds a method to optionally detect disk, network, and env access access during a build and write this to a file. ### Why? This will be consumed by Turborepo to determine **if** a build can be cached, and if so, **how** it should be cached. ### How? This implements a proxy that can be selectively applied to functions to watch their access to disk, network, and env. For Turborepo, we only care about what can alter the build output, to achieve this, we trace the config load, and the static page generation.
