refactor(core): stop exporting `NOTIFICATION_HEADER`

fix(core): stop `merge_content` from changing the first message's content (#41502) When a model streams a reasoning block or other list content and a later step in the chain also adds up the streamed chunks, the model's traced output repeated the first piece of text after it: `HelHello world` instead of `Hello world`. `merge_content` appended to the content list of the first message it merged, so the merge changed that message. A model's own `stream()` and the step after it add up the same chunk objects, so the second addition found text the first had already appended to that list. `merge_content` now copies the list before adding to it. The fix was proposed in #38600 by @Vedant-Agarwal (reported in #38601), and the direct `merge_content` test is the one he suggested in review. This PR first also changed how chains add up streamed chunks, for #40826. #41468 fixes that where chunks are added, so that part is gone. ## Release note A model's traced output no longer repeats text that follows a reasoning block or other list content when the stream goes through a later step.
