tests/integration/find-*.test.ts and tests/unit/brainy/find*.test.ts each
opened one or more Brainy instances (via beforeAll/beforeEach) and never
closed them — the leaked instance's cadence timer stays armed for the rest
of the single-forked vitest run and keeps narrating into every later file.
find-unified-integration.test.ts was a real bug, not just a missing hook:
its afterAll called a no-op TestCleanup().cleanup() (nothing was ever
registered with it) and then discarded the brain reference with
`brain = null` — the brain was never actually closed.

The proximity search fetched its anchor through get(), which omits vectors
by default, then handed a zero-length vector to the index — every
find({ near }) refused with a dimension mismatch, for every caller. Found
by the Rust planner's first-contact pins comparing outcomes with and
without the planner on a refused shape. The anchor is now fetched with its
vector, and an anchor that has none refuses by name — a proximity search
around an unvectored row has no meaning and must not fail inside the index.
Pinned in tests/integration/find-near.test.ts.
