"""Regression guard: shipped code must not reference old project names.

The FabledScryer -> Roundtable -> Steward renames repeatedly left stale package
imports behind in the (then separate) plugins (e.g. `from fabledscryer.models...`),
silently breaking every non-host_agent plugin. Now that plugins are folded in-tree
and version with core, this test fails loudly if either legacy name reappears in
the shipped Python / templates / plugin manifests.
