/**
 * The docs the dev server has read from the project's own source, one entry
 * per transformed module, joined into `ComponentDocs` on demand.
 *
 * Inheritance is resolved at read time rather than when a module is stored:
 * a base class may be transformed after its subclass, and an edit to it
 * should show in every subclass without re-reading them. A superclass is
 * followed while it is in the index (same module by name, another module
 * through the import id the plugin resolved) and the walk stops at the first
 * one that isn't, such as `LitElement`. A class's mixins come before its
 * superclass, outermost first, each followed the same way and stepped over
 * when it isn't in the index (`SignalWatcher` from a package). Members a
 * subclass redeclares win.
