- #63200: Empty-content assistant messages with tool_calls break DeepSeek API (HTTP 400)

The three members appear to concern assistant messages that have empty content alongside tool_calls, which is reported to cause an HTTP 400 error from the DeepSeek API. Two titles describe agent-side changes (stripping such messages or normalizing empty content to None); the titles alone do not show whether either approach works or has been merged.

## TL;DR
