Merge branch 'dev' into otto/secrt-2035-thinking-indicator-between-streams

Change ToolUIPart.state check from "result" (invalid) to "output-available"
(the actual AI SDK state for a completed tool call). This fixes the build
and makes the thinking-between-tool-calls feature functional.

Also simplifies the IIFE into a plain local variable for readability.
