## Summary
- Adds comprehensive feature plan for app icons/emoji system
(`plans/app-icons.md`)
- Every app gets a visual identity (emoji or GitHub-style generated
avatar) shown in chat tabs, sidebar, and app details
- Chat tabs become condensed single-line layouts (icon + chat title) for
better density
- Plan covers data model, UX flows, accessibility, backfill strategy,
and phased implementation

## Test plan
- [x] Markdown renders correctly
- [x] All lint/type checks pass
- [x] No code changes, plan document only
