Kao is a display, not a monitor — external systems push events via REST
rather than Kao polling things itself. Update CLAUDE.md to reflect this:
- New Design Philosophy section making the REST-first approach explicit
- Architecture diagram updated to show external systems as the push source
- Detectors section demoted to "Legacy Detectors" with a note to prefer push
- TODO.md added with planned REST API improvements (SSE, notify queue,
sticky notifications, named presets, batch notify, /history endpoint)
and display improvements (brightness curve, scrolling ticker)
