Test Optimization

Advanced test optimization with cargo-nextest, property testing, and benchmarking.

cargo-nextest (Primary Test Runner)

cargo nextest run --all              # all tests
cargo nextest run --profile ci       # CI with retries + JUnit XML
cargo nextest run --profile nightly  # extended timeouts
cargo nextest run -E 'package(do-memory-core)'  # filterset DSL
cargo test --doc --all               # doctests (nextest limitation)

Configuration (.config/nextest.toml)
