Adds three intent-level graph reads to the `brain.graph` namespace, each
native-dispatched to the optional `@soulcraft/cor` 3.0 graph engine when present
and served from pure-TS kernels otherwise (identical public shapes, default
visibility filter respected on both paths):
- `rank(opts?)` → `{ id, score }[]` descending — importance / centrality.
TS fallback: PageRank power-iteration with dangling-mass redistribution.
- `communities(opts?)` → `{ groups, count }` — connected grouping. TS fallback:
union-find weakly-connected components, or iterative Tarjan SCC when
`{ directed: true }`.
- `path(from, to, opts?)` → `{ nodes, relationships, cost } | null` — best route.
TS fallback: BFS for fewest hops, Dijkstra (min-heap) for least summed edge
weight (`by: 'weight'`); on-demand frontier expansion so short paths terminate
early. `direction` / `type` / `maxDepth` filters apply.
These are intent contracts, not algorithm contracts — the question is the
promise, the algorithm is the engine's choice.
Pure kernels live in src/graph/analyticsFallback.ts (PageRank, connected
components, Tarjan SCC, MinHeap) — unit-tested in isolation. The full surface is
tested end-to-end through the TS fallback, and the native dispatch + int↔uuid
hydration paths are covered by a mock provider in graph-native-routing.
