The ai-elements `reasoning.tsx` imports `streamdown`/`@streamdown/*`, which are
not installed (it's a dormant component). Importing it into chat-panel made the
whole chat fail to render — taking the input toolbar (attach, add-patient, model
picker, mic, send) down with it.
Render the reasoning block with a self-contained COSS Collapsible + Shimmer
instead (no streamdown). The other AI-elements I wired in (tool, queue,
suggestion, shimmer) have their deps installed and stay. Verified with a full
`next build`.
