Operator decision 2026-08-24: rather than making two hub instances coexist
safely, retire the second one. The local postgres+uvicorn instance is what
impersonates central and is redundant with ADR-010 decision 3 plus Repo
Manager's file-derived index.
With it gone, state-hub-primary binds 127.0.0.1:8000 unchanged and every
existing default becomes correct with no call-site edits.
Adds the cache-only recovery export (44 records) as the T05 source.
