Implement ＠defer "June 2023" response format

[BoD]

Implements the latest (as of 2024-12-17) ＠defer incremental response format as seen in examples and spec edits.

This shouldn't be merged as-is, as at least the end-to-end tests with the Router will fail.

There may be a way to have both the "old" (20220824) and latest formats working but not sure this would be useful.
