Summary

With recent changes to the custom component interface, it's now possible to remove all runtime reliance on NPM. Doing so has many virtuous knock-on effects:

1. Removal of large chunks of code
2. Greatly simplifies how users dynamically experiment with React component libraries, because their usage no longer requires a build step. Instead they can be loaded in the browser from a CDN that distributes ESM modules.
3. The built-in client code needs to make fewer assumption about where static resources are located, and as a result, it's also easier to coordinate the server and client code.
4. Alternate client implementations benefit from this simplicity. Now, it's possible to install idom-client-react normally and write a loadImportSource() function that looks for route serving the contents of IDOM_WEB_MODULES_DIR.

This change includes large breaking changes:

• The CLI is being removed as it won't be needed any longer
• The idom.client is being removed in favor of a stripped down idom.web module
• The IDOM_CLIENT_BUILD_DIR config option will no longer exist and a new IDOM_WEB_MODULES_DIR which only contains dynamically linked web modules. While this new directory's location is configurable, it is meant to be transient and should not be re-used across sessions.

The new idom.web module takes a simpler approach to constructing import sources and expands upon the logic for resolving imports by allowing exports from URLs to be discovered too. Now, that IDOM isn't using NPM to dynamically install component libraries idom.web instead creates JS modules from template files and links them into IDOM_WEB_MODULES_DIR. These templates ultimately direct the browser to load the desired library from a CDN.
