Subject: [PATCH] feat(api): include unified diff in DE summary prompt and
 extend timeout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add getLastCommitDiff to fetch the latest commit’s unified diff and
append it to the system prompt for German summaries. Increase LLM call
timeout to handle larger prompts.
