 * Per-SmartdataDb collection cache.

 * Historically this class keyed its cache by class name alone, which meant
 * the first SmartdataDb to request a collection of a given class name
 * "won" — every subsequent call from a different SmartdataDb instance
 * received the cached collection bound to the first db. That silently
 * broke multi-tenant SaaS apps (one db per tenant), tests instantiating
 * multiple SmartdataDbs in sequence, and any in-process db cluster switch.
 *
 * The cache is now keyed by `(SmartdataDb instance, className)` using a
 * WeakMap of db → Map<className, SmartdataCollection>. Entries are GC'd
 * with their parent db automatically.
