Multiple databases

The flagship dual-DB story.

ReportKit does not own your connections. The host configures mysql + mysql_archive (or any names). Core provides:

1. MergedRowSource — fetch from N sources, merge, dedupe, sort
2. PseudoPaginator — page the merged set for DataTables
3. Optional getTrace() — per-source counts + timings for debugging / demos

See the live demo for a Cloudflare D1 simulation of this flow.
