Chat context indicators — show when agent recalls memory #364
Description
Context
Follow-up from #277 (session-memory-visibility). Chat currently shows no indication of memory usage.
Goal
Add subtle "agent recalled context" indicators in chat messages so end users know when the agent is using remembered information, without overwhelming them.
Scope
- Add a small indicator (icon/badge) on messages where memory was recalled
- Tooltip or expandable section showing which memory was used
- Keep it non-intrusive — no memory content dumped into the chat
Acceptance Criteria
- Chat messages show a subtle indicator when memory was recalled
- Users can optionally see which memory entries influenced the response
- Indicator is non-intrusive and doesn't clutter the chat UI
