v0.6.0

Added

• Datadog deep-links on grouped Errors rows (search by job class) — failures that only surface in Errors can now jump to Datadog.
• RoundhouseUi.poll_interval (default 5s) — configurable dashboard poll cadence; slower polls cut host auth/routing load.

Changed

• Throughput chart buckets by a configurable interval (per 10s/30s/1m/5m) — a point lands once per interval, so it reads as a sustained line, not a per-poll sawtooth.
• Dropped the hardcoded ▲ up-arrow on the Processed rate.
