 * Compact date labels for dense table rows (`Jul 31`, `Jul 31 14:22`).

 * features render it — logs, credit usage, and audit logs — and the previous
 * home (`app/workspace/[workspaceId]/logs/utils.ts`) also exports registry-backed

 * `@/blocks/registry` → all 282 block configs → the tool registry into every
