Expand description

Build a FunctionDecl from a bare function ident or a path:

fun!(foo) — a #[prebindgen] fn; its signature is read from the registry.
fun!(crate::foo) — a binding-local fn: any fn the binding crate defines, exported through the same machinery as a #[prebindgen] one. A path carries no signature to read, so chain .sig(sig!(…)). The generated file calls it by the declared path (it compiles inside the binding crate, so crate::-rooted paths resolve).
