Remove vestigial notification panel

[TraderSamwise]

Summary

• remove the old notification-panel overlay, routing, adapter methods, and event-stream refresh hook
• delete the local production Coordination builder so the TUI only applies service-shaped Coordination payloads
• update dashboard visible labels from workflow wording to Coordination wording

Verification

• yarn vitest src/multiplexer/notifications.test.ts src/multiplexer/project-event-stream.test.ts src/multiplexer/dashboard-view-methods.test.ts src/tui/screens/dashboard-renderers.test.ts
• yarn typecheck
• yarn lint
• yarn build
• yarn vitest
• pre-push hook: yarn typecheck && yarn lint && yarn test

📝 Walkthrough

Walkthrough

The PR removes the "notification-panel" overlay kind, NotificationPanelState interface, and all associated render/open/close/key-handle functions. Notification state is now populated exclusively via a service-driven refreshCoordinationFromService path. Dashboard wiring, event stream triggers, UI activity chip labels, and tests are updated to match.

Changes

Notification Panel Removal and Coordination Refresh

Layer / File(s)	Summary
Type and state contract removals src/dashboard/state.ts, src/multiplexer/index.ts	"notification-panel" removed from DashboardOverlayKind; NotificationPanelState interface and notificationPanelState field removed from Multiplexer.
notifications.ts: remove panel exports, promote coordination refresh src/multiplexer/notifications.ts	Imports reorganized, CoordinationPayload defined earlier with updated docs; all six notification-panel exported functions removed; module now centers on refreshCoordinationFromService which validates service payload before applying via applyCoordinationModel, returning false on failure.
Remove notification panel overlay renderer src/tui/screens/overlay-renderers.ts	Theme imports narrowed (drops modalBand, padVisible, statusDot); buildNotificationPanelOverlayOutput and renderNotificationPanel exports deleted.
Dashboard control, view, and actions wiring src/multiplexer/dashboard-control.ts, src/multiplexer/dashboard-view-methods.ts, src/multiplexer/dashboard-actions-methods.ts, src/multiplexer/project-event-stream.ts	"notification-panel" key-handling and overlay-output branches removed from dashboard-control.ts; notification-panel wrapper methods removed and syncTuiNotificationContext hardcoded to false in dashboard-view-methods.ts; action method renamed from refreshNotificationPanelFromService to refreshCoordinationFromService; event-stream swaps notification-panel conditional refresh for a graveyard-screen conditional.
UI label rename: Workflow → Coordination src/tui/screens/dashboard-renderers.ts	Three session activity chip texts and one details-panel key label changed from "workflow …" / "Workflow" to "coordination …" / "Coordination".
Test suite: switch to applyServiceLikeCoordinationPayload src/multiplexer/notifications.test.ts	Imports updated; new applyServiceLikeCoordinationPayload helper introduced; all refreshNotificationEntries(host) calls across six test scenarios replaced with this helper.

Poem

🐇 Hop hop, the panel has gone away,
No notification drawer to display!
Service-driven coordination's the route,
Old "workflow" chips now shout "coordination" out.
Cleaner code under this bunny's paws today! 🎉
