VM and transpiler for Aver, a statically-typed language designed for AI-assisted development

//! WASM runtime entry point.
//!
//! Every runtime fn (alloc/heap GC, obj inspection, str/list/map/vec
//! ops, numeric formatting) lives in the WAT runtime under
//! `runtime/wat/*.part.wat` and is imported by user.wasm from the
//! `aver_runtime` module. This Rust crate just exposes the index
//! tables (`indices`) and the WAT → wasm bytes builder
//! (`wat_module`).
//!
//! Under `--target wasm --bridge wasip1`, an additional shim module
//! (`runtime/wat/aver_to_wasi.wat`) translates `aver/*` host calls
//! into `wasi_snapshot_preview1.*` so the program runs standalone
//! under wasmtime.
