User story

As an operator I want one-click Cancel, Pause, and Fork-to-new-task actions directly on each agent card (board, monitor, drawer header), so I can interrupt runaway runs or branch a long thread without leaving the dashboard.

Acceptance criteria

Cancel

Already exists per postCancel; surface as a button on the agent card with an icon (<lucide.Square />) and toast confirmation.
Confirms inline (Are you sure? ghost popover) — single-click cancel was a footgun in agents-architecture.md history.

Pause

New action: pauses the agent at the next safe boundary (between turns / tool calls). Server marks task paused, the runner halts before the next event without dropping the session.
Resume button replaces Pause when paused.
Distinct from Cancel — pause keeps the worktree, session, and event log intact.

Fork

New action: snapshot the current run (events, session id, worktree commit ref) and dispatch a fresh task on a new issue with a "Forked from #N at event K" preamble.
Operator picks the agent type for the fork (default: same as parent).
The original run continues unchanged.

Frontend

Button group on every agent card / drawer header. Icons via lucide. <Button tone="ghost"> for Pause/Fork; tone="error" for Cancel.

Out of scope

Cross-host fork (we're single-host).
Time-travel fork ("fork from event K-50") — only fork-from-now supported.

Dependencies

None hard. The status pill ticket should land first so paused state has a label, but not a blocker.
