📋 Summary

Sprint: Sprint 226 · Dashboard internationalization foundation · Task: T17

Establish a dashboard-only English/German internationalization system with persisted locale selection, complete German coverage across every dashboard route and overlay except English documentation bodies, locale-aware formatting, and automated coverage checks while preserving backend contracts and runtime/API-authored messages verbatim.

📝 Full Task Prompt

## Objective
Internationalize the feature-gated Nodes route while preserving graph schemas, node commands, validation identities, and provider execution payloads.

## Scope
- Create `dashboard/src/v2/i18n/messages/nodes.ts`
- Edit `dashboard/src/v2/NodesPage.tsx`
- Edit all files under `dashboard/src/v2/components/nodes/`
- Edit presentation behavior in `dashboard/src/v2/lib/node-flow-view-models.ts`, `nodes-canvas-state.ts`, and `nodes-agent-surface.ts`
- Verify `node-flow-api.ts` without translating response/error payloads
- Update node page, canvas, flow, inspector, debugger, validation, and accessibility tests

## Implementation Requirements
1. Translate page headers, libraries, palettes, toolbar controls, inspector fields, port labels, governance states, validation summaries, run/debug controls, scheduling actions, dialogs, empty/loading/error states, and accessible names.
2. Keep node IDs/types, widget schema keys, command names, configuration values, graph JSON, skill names, run logs, provider output, validation entity IDs, and API errors verbatim.
3. Preserve localStorage migration, project scoping, dirty detection, graph serialization, validation ordering, run cancellation, retry, selection, panning/zoom, minimap, and keyboard behavior.
4. Test German create/edit/validate/run/debug/schedule paths, invalid graphs, provider/network failures, cancellation, stale runs, legacy migration, long labels, and mobile/keyboard operation.

## Constraints
- Do not change node-flow contracts, API routes, feature flags, graph persistence, migration markers, or execution semantics.
- Translate dashboard-generated validation explanations only; never rewrite server/provider diagnostics.
- Do not alter stable node field values to match translated labels.

## Verification
- Run focused Nodes page, canvas, flow, inspector, debugger, and validation tests.
- Run `pnpm run lint`.
- Run `pnpm run test:dashboard`.
- Run `pnpm run build`.
- Success means the entire feature-gated node workflow is German and graph/API payloads remain compatible.
