Counter metrics like chunks.exported.count are monotonically increasing.
Add mode=delta query parameter to the agent metrics API that computes
per-bucket deltas server-side using ClickHouse lag() window function:
max(value) per bucket, then greatest(0, current - previous) to get the
increase per period with counter-reset handling.
The chunks exported/dropped charts now show throughput per bucket
instead of the ever-increasing cumulative total.

Upgrade @cameleer/design-system to ^0.1.3 which adds LIVE/PAUSED
toggle to TopBar backed by autoRefresh state in GlobalFilterProvider.
Add useRefreshInterval() hook that returns the polling interval when
auto-refresh is on, or false when paused. Wire it into all query
hooks that use refetchInterval (executions, catalog, agents, metrics,
admin database/opensearch).
