legacyCompat.getVersion(): { version: string; homepage: string; }
LANraragi::Utils::Generic::get_version — legacy reads this straight out of its own
package.json (version/homepage fields) once and caches it; this returns the
equivalent static values for this project instead of trying to read a Rust crate's
Cargo.toml from within the Deno sandbox. Update these two literals if
Cargo.toml's [workspace.package] version/repository ever changes.
