fix(apps): resolve dangling acorn type imports in node-runtime

After the declaration shims were removed, operations.ts still imported
two names that only existed in those shims: `AcornFunction` (the real
acorn export is `Function`) and `FullAncestorWalkerCallbackWithState`
(the real acorn-walk export is `FullAncestorWalkerCallback`). Point the
imports at the real package exports so the AST module typechecks.
Types-only change; no behavior change.
