Finance ERP showcase powered by CopilotKit deep agents. Includes a
Next.js 16 frontend with 7 CopilotKit-registered tools, a LangGraph
multi-agent backend (orchestrator + research/projections subagents),
Postgres-backed dashboard gallery with 12 widget types and 4 templates,
and human-in-the-loop approval flows for invoices and inventory.
Adds a minimal demo at /a2ui-demo that uses the demo-button agent to
reproduce and validate the A2UI thread-clone bug fix. The agent renders
an A2UI surface with a Confirm button on first run; clicking it fires a
second run that emits a text confirmation message.

Follow-up to #3607 — the same problematic `import { v0_8 } from "@a2ui/lit"`
pattern existed in 4 example files. Switch to `@a2ui/lit/0.8` subpath for value
imports and remove an unused v0_8 import. Also broaden the lint rule glob to
cover `examples/` and prevent regression.

These images were committed as raw binaries on main despite
