THEN Apply a patch to node_modules/pkce-challenge/dist/index.node.js to wrap the top-level await in an async IIFE, or switch the entire project to ESM. Use patch-package to persist the fix.

// In node_modules/pkce-challenge/dist/index.node.js, replace:
// (await import("node:crypto")).webcrypto;
// with:
// (async() => { (await import("node:crypto")).webcrypto; })();
