Description

Currently, cargo execute scrips before the build starts with the build field. I propose renaming build to pre_build and adding post_build (which would run after every successful build). It's useful for general postprocessing: running executable packers, zipping files, copying stuff, logging, etc.

Research direction

Start by tracing Cargo's existing build-script configuration and how the build field is executed before compilation. Determine the design and compatibility impact of renaming it to pre_build and adding post_build after successful builds. Done means the lifecycle behavior and migration expectations are defined and covered by appropriate Cargo tests.
