Subject: [PATCH 1/2] Python: fix(anthropic): nest bash tool result files
 inside the shell tool result

The bash branch appended hosted output files to the message-level
contents list instead of the shell result outputs, so the files leaked
out as bare top-level hosted_file contents. The code interpreter twin
branch already nested them correctly.

Fixes #9342
