Go moves toward cgo without a C toolchain

The accepted proposal to add a cgobindings GOEXPERIMENT is the groundwork for cgo without a C toolchain, which would quietly fix one of the longest-standing papercuts in cross-compiling Go. Alongside it, debug/pe.ImportDirectory is being deprecated after fifteen years of being unusable, which is the kind of housekeeping that only happens when someone finally admits defeat. Elsewhere, a video walkthrough of Go 1.24's Swiss Tables map implementation is making the rounds for anyone who wants to understand what the control bytes are actually doing.
