What problems was I solving

The public index of @architect/field-agent-ui-react re-exported FieldAgentPageComponentRenderer and type ComponentStreamingState, but neither symbol had any consumer of this package. One re-export was added after its only caller was already deleted, and the other was dead from the moment it was added, leaving misleading public surface area.

What user-facing changes did I ship

None. There are no user-facing changes; this only narrows an unused public API surface.

How I implemented it

Deleted the two named re-export lines from architect/field-agent-ui/react/main/index.ts only. The underlying symbols remain exported by @architect/page-rendering-react/field-agent-components, and internal page-rendering-react consumers import them directly from that package. No other files needed updates.

Description for the changelog

Removed two unused re-exports (FieldAgentPageComponentRenderer and type ComponentStreamingState) from the @architect/field-agent-ui-react package index. The symbols remain available from @architect/page-rendering-react for internal consumers, and no runtime behavior or package-consumer updates are required.
