Tests no longer sit next to the implementation. They import the package through ../src, the root tsconfig still type-checks them, and the package build and declarations cover only src/.

Benchmarks
Compares core-v2's performance against an earlier implementation (by default
main).
From the repository root:
packages/core-v2/verify/setup-baseline.sh main # extract into verify/.baseline/
ONLY=baseline npx vitest bench --run --config packages/core-v2/verify/vitest.config.ts
ONLY=rewrite npx vitest bench --run --config packages/core-v2/verify/vitest.config.ts
scene.bench.ts measures compositing, push/back cycles, and rendered frames.
Run each implementation in its own process with ONLY=; running both in one
process biases whichever runs second.
Behavioural verification lives with the unit tests: tests/property.test.ts
drives random operation sequences and pointer streams and checks the scene's
structural invariants after every step. Set PROPERTY_SEEDS to run more.
