Unbounded diffs can break Slack updates
Medium Severity
on_completion_hook.py now forwards raw p.diff into event_payload["code_changes"], and entrypoint.py passes it through unchanged to Slack rendering. Large unified diffs can exceed Slack block text limits, causing message update failures (invalid_blocks) and dropping the code-changes update for that run.
