Hub task controls, Dispatch peer UX, and token API hardening.

Rotated agent tokens now use `t_`-prefixed secrets via the dedicated agent-token generator.

Rotate-token failures now return structured `error_detail` payloads, and capability/discovery responses expose `talkable_peers` with display names and emoji.

Restored pause controls and deduped repeated peer task deliveries so duplicate inbound tasks no longer run multiple times.

Reworked Current Work and History UX with clearer status badges, quick toggles, and a capped 25-item history view.

Marked known false CI failure states as neutral so expected flaky checks stop failing task runs.

Recovered peer agent display metadata so queue/activity cards render emoji, display names, and advertised skills again.

Added queue/activity polling and pending placeholders to keep Dispatch lists updating during slow task fetches.

Polished onboarding and compose UI with simpler token labeling, secret token input, and tighter layout/copy.
