vnd:*: Vendored crate modules

The vnd:* namespace exposes individual Rust crates to Lua. Each module wraps exactly one upstream crate, and the module name matches the crate name verbatim. There is no renaming, no aliasing, no merging of crates into composite modules — require("vnd:hyper") always means the hyper crate, and never anything else.

This naming rule is non-negotiable. It is what lets scripts reach for an upstream crate by its real name, find its real surface (modulo Lua adaptations), and locate its real documentation without indirection.
