Ruchy backend.
Lowers meta-HIR to Ruchy source. v0.1.0 emits the same arithmetic
subset as xpile-rust-codegen — the surface difference is
fun ... -> T { ... } instead of Rust’s pub fn ... -> T { ... },
and floor-div / modulo still go through Euclidean semantics
(div_euclid / rem_euclid).
Future scope (tracked by Profile::RuchyOut): reconstruct the
pipeline operator |> and DataFrame-flavored sugar from meta-HIR
patterns. See docs/specifications/sub/bidirectional-ruchy.md.
