Subject: [PATCH] :sparkles: Add datascript dependency for graph-overlay

First step of the graph-overlay port: index identity, type and topology
in datascript over the document, instead of projecting every shape
attribute into a Ladybug database. Backend and frontend both declare it,
because the index is meant to end up in the derived-index worker.

Measured motivation (devenv, JVM datascript 1.8.1): a 20k-shape file
indexes in 1.1s and 5.7MB, against 33-43s and 144MB for the equivalent
Ladybug session.
