Three layers:
1. GFM markdown — add remark-gfm so tables, task lists, strikethrough,
autolinks render properly. Style table elements (overflow-aware
container, muted header, divider rows). Render `[ ]` task list items
as visible checkboxes.
2. Structured tool-result rendering — new `tool-result-renderers.tsx`
dispatches by tool name to render a small UI block beneath each
ToolCallCard:
- list_tenants → table with status pills + plan column
- get_tenant → tenant detail card
- get_platform_stats → KPI tiles (total + per-status)
- list_audit_log → timeline rows with actor_type + action
- list_users → user list with role chips
- suspend_tenant / activate_tenant → tenant card with action confirm
ToolCallCard collapses by default — operators expand for raw JSON.
3. Custom ```card``` blocks the LLM can emit inline:
- {"kind":"pill","status":"…"} — status pill
- {"kind":"stat","label":"…","value":…} — stat tile
- {"kind":"callout","tone":"info|warning|danger|success",…} — callout
Malformed blocks fall through to the prose unchanged. Client strips
well-formed blocks from prose and renders them as components.
Domain primer updated to teach the model the card schemas and remind it
NOT to re-render tool-result data as markdown tables (that's done
automatically — it should add commentary only).
Layers are independent: 1 + 2 always work; 3 is purely additive.
