- Fix `import.meta.env.DEV` crash in graphSceneState.ts that broke the
entire test:graph-workspace suite (module load fails in Node.js/tsx)
- Export `resolveGroupedDisplayNodeId` from graphSceneState.ts and
remove the identical copy in GraphWorkspace.tsx
- Add `checkGroupedViewAvailability` helper (Louvain only, no centrality)
so grouped view availability can be checked cheaply on every graph change
- Gate full community graph build (`groupedDisplayCandidate`) on
`viewMode === 'grouped'` to avoid running Louvain + centrality on every
graph version tick when the user is not in grouped view
- Remove dead ternary in `focusNode` where both branches returned `nodeId`
- Add 7 new tests covering resolveGroupedDisplayNodeId,
resolveGroupedDisplayStateSnapshot, and checkGroupedViewAvailability
