osobhandClaude Opus 5.5 1b3bbb054a perf(agent): cache the knowledge graph's adjacency index ...

bfs_neighbors and spreading_activation built an adjacency index over the
whole graph on every call (1efd82c), so a 2-hop BFS over 1K entities
paid to index every entity and relation first: 155 us, 6.5x the 24 us
the README quoted. Found by the dated benchmark re-run.

The index is now cached on KnowledgeCache and checked against a
fingerprint of the graph on each use — one pass over entity ids and
relation endpoints, no allocation — so any change, including direct
edits of the public entities/relations Vecs (schema.rs's load path
pushes to them), still triggers a rebuild. A test edits the graph
directly in every way (push, in-place rewire, pop + push at equal
length) between traversals.

tank, 2026-09-24: BFS 1K entities 155.1 -> 23.1 us, 100 entities
17.5 -> 5.23 us, spreading activation 100 22.8 -> 10.1 us.
