Update jotai to 3

`jotai` stayed on ^2.20.1 in the latest dependency sweep. 3.0.0 breaks the build in two ways.
(`jotai-family` is already on ^1.1.0 and needs no further change.)

## Blockers found

**Removed subpath** — `packages/graph-explorer/src/core/queryClient.ts:1` imports from
`jotai/vanilla/store`, which no longer exists in v3: `error TS2307: Cannot find module
'jotai/vanilla/store'`. Needs the v3 equivalent for whatever store type it pulls in.

**Inference regressions** — 6 × `error TS7006` implicit `any` on callback parameters, all in the
bulk/search query modules:

- `connector/queries/bulkEdgeDetailsQuery.ts:59, :64`
- `connector/queries/bulkVertexDetailsQuery.ts:59, :64`
- `connector/queries/bulkNeighborCountsQuery.ts:53`
- `connector/queries/searchQuery.ts:34`

These are likely downstream of the store type import failing rather than six independent problems —
fix the import first and re-measure.

## Acceptance

`pnpm checks` and `pnpm test` pass with jotai at 3.x.

Start at packages/graph-explorer/src/core/queryClient.ts:1 and verify which store type the removed jotai/vanilla/store import provides. After updating the dependency to 3.x, recheck the listed bulk and search query modules for the TS7006 errors, then run pnpm checks and pnpm test; done means both pass.
