Patch Changes

• 2958540: fix(ui): export isDynamicToolUIPart from ai package

• aa2dbe6: Fix: convertToModelMessages no longer emits an empty assistant message when a block contains only unknown data parts (e.g. a data part before step-start with no convertDataPart provided)

• faaef7c: fix(ai): enforce timeout.stepMs for the whole step in streamText

  Previously streamText's step timer was cleared synchronously right after the step's stream was registered, before the stream produced anything, so stepMs never aborted a step that stalled before emitting content. The step timer now survives until the step's stream finishes or aborts, matching generateText. chunkMs/totalMs and normal step-finish cleanup are unchanged.

• 45a9cbf: Return validated elements from generateText array output

• 2706461: fix(ai): include tool input on tool result for provider executed dynamic tools

• 327642b: fix: more precise default message for tool execution denial

• 89df298: Preserve signed tool approval metadata when recording approval responses.

• 8ed1f83: fix(ai): tag step/chunk timeout aborts with TimeoutError reason

  When timeout: { stepMs } or timeout: { chunkMs } fires, the abort reason is now a TimeoutError DOMException, matching what AbortSignal.timeout() produces natively. Consumers can distinguish a framework timeout from a user-initiated cancel via signal.reason.name === 'TimeoutError'.
