PR Summary

Low Risk
Additive build-step behavior with an empty default; only affects output when paths are configured, similar to legacy-html.

Overview
The web generator gains an additionalPathsToCopy config option (default []) so projects can copy static directories (e.g. assets) into the build output alongside HTML, JS, and CSS—without tying paths to page content.

After writing pages and bundles, generate invokes a new copyAdditionalPaths helper that recursively copies each configured path into output under its basename. Types, defaults, and README document the option; a unit test covers the copy behavior.

@avivkeller yeah it's fully IA. I received same thing on nodejs/userland-migrations

You're right, this duplicates #753. Closing it; I should have checked that first.
