[WIP] Fix images not rendering when summarizing an issue

[Copilot]

Fix Images Not Rendering When Summarizing Issues/Notifications

Plan:

• [x] Analyze the issue - Images in markdown format (![alt](url)) are not being rendered in the notification/issue summary output
• [x] Identify root cause - The LLM summarization instructions don't include guidance to preserve images in markdown format
• [ ] Update summarizeNotificationsTool.ts to add instructions for preserving images in the output
• [ ] Update summarizeIssueTool.ts to add instructions for preserving images in the output
• [ ] Test the changes manually to verify images render correctly
• [ ] Run linter and fix any issues
• [ ] Request code review
• [ ] Run security scan
