// Node-CJS shim wrapping the compiled .wasm module so VS Code's extension
// host (or any CJS consumer) can require() it directly.
//
// Issue #35 Phase 1 — no vscode API bindings yet (that's Phase 2 via
// stdlib/Vscode.affine). The Wasm module's `activate` and `deactivate`
// exports become exports.activate / exports.deactivate.
