The plan §12 previously specified tests/ at root with integration/
and chaos/ subdirectories. However, the actual implementation uses
the idiomatic Rust convention with tests in crates/*/tests/.
This commit:
- Updates plan §12 repository structure to document the actual layout
- Moves tests/benches/score-comparability to docs/research/ (research artifacts)
- Removes the now-empty tests/ directory
CI already runs cargo test --all --all-features which correctly
discovers and runs all crate-level integration tests.
