Owen Lin e7d0e14172 Repair unterminated rollout files before appending (#32276) ...

## Why

Appending directly to a non-empty rollout that lacks a trailing newline joins the
next JSON object to the existing record, producing invalid JSONL.

## What changed

- Ensure non-empty rollout files end with a newline before opening them for
  append, including resumed, compressed, and direct append paths.
- Perform the synchronous tail inspection outside the async runtime.

## Testing

- Add a regression test covering newline repair and repeated opens.
