fix(common): fix @endo/common integration breakage

-Each utility is in its own source file, named after the main export of that utility. (This is often that file's only export.) This enables importers to bypass this package's `index.js` and just do a deep import of what they need.
+Each utility is in its own top-level source file, named after the main export of that utility. (This is often that file's only export.) The `package.json` also lists each as a distinct `"export":`. There is no `index.js` file that rolls them together. Thus, each importer must do a deep import of exactly the export it needs. Some implementations (bundlers, packagers) can thus do tree-shaking, omitted code that isn't reachable by imports.
+
+Currently there are no `src/something.js` files. The only source files that would go in `src/` are those that do not represent separately exported utilities.
 
 Generally each utility also has its own test file. (An exception is that `make-iterator.js` is indirectly but adequately tested by `test-make-array-iterator.js`).
