Tested image attachment flow via Playwright MCP. Found three issues:
1. Agent creation silently drops images (by design - TODO in code)
2. Web platform fails base64 encoding (expo-file-system not available)
3. Server buildAgentPrompt only creates text summary, never sends bytes
Added fix tasks to plan.md and detailed report in
REPORT-image-attachment-investigation.md.
