jif c117207a6f Drop descendant channel posts from retained remote compaction v2 history (#47249)
## Why

Remote compaction v2 excluded descendant progress messages from retained history but kept `CHANNEL_POST` messages from those same agents.

## What changed

Treat descendant `CHANNEL_POST` messages like `MESSAGE` progress updates when selecting history to retain after remote compaction v2.

## Testing

Extend the remote compaction test to verify that a child channel post is included in the compaction input and omitted from the follow-up request.
