feat: power reference site with in-process WIP WASM

Add the public-document Worldspace, Rust Client/Host bridge, and WIP-backed tree and document rendering while preserving static fallback and navigation. Pin the Rust source and build tools, verify resource and trap boundaries, and cover dev and preview loading including same-origin generated module URLs.
