fix: wire conversation panel to DAG nodes with toggle support

- Add MessageSquare icon to GraphNodeCard; prop-thread onConversationOpen
  and selectedTaskId through WorkflowGraph node data (no useUrlState
  inside ReactFlow nodes — avoids context/timing issues)
- Fix ContextualRightPanel: check taskId before epicId so clicking the
  conversation icon always opens ThreadDrawer even when an epic filter
  is active
- setEpicId now clears task from URL so selecting an epic resets any
  open conversation thread
- handleGraphSelect toggles: second click on same node calls setTaskId(null)
  closing the right panel
- Add onSelect to WorkflowGraph flowModel deps to prevent stale callbacks
- Fix ContextualRightPanel onClose no-ops: wired to setTaskId(null) /
  setSwarmId(null) so back button works
- Right panel always visible (removed panel==='open' gate in UnifiedShell)
- SmartDag task grid: horizontal scroll, fixed-width cards, hideClosed=true
- Add <Suspense> in page.tsx for useSearchParams compatibility
- Enable dolt auto-start in .beads/config.yaml
- Add 14 static analysis tests (graph-node-conversation.test.tsx)
