fix(anthropic): merge consecutive assistant messages with mixed content types

When two consecutive assistant messages had mixed content types (one
string, one list), the merge logic just replaced the earlier message
entirely with the later one (fixed[-1] = m), silently dropping the
earlier message's content.

Apply the same normalization pattern used in the tool_use merge path
(lines 952-956): convert both to list format before concatenating.
This preserves all content from both messages.
