Summary

• Launch Windows scripted test engines through Node-compatible entrypoints; retain POSIX shebang execution.
• Add launch/protocol regressions and the Rust tests’ Node dependency.

Closes #336

Risk/rollback: test-launch or CI dependency regressions; revert the merge commit.

Parity rows

O27: functional Windows replay now passes; reference comparisons and quiet-machine qualification remain outstanding.

@kinqsradio ready for review. All configured checks are green on f099d8d3aaefac39b9a3334085c0893b77405e41. The new native scripted-engine regressions ran and passed on Windows and macOS; the unchanged O27 browser case also passed on Windows and reached its final END message.

This fixes the Windows script-launch failure and declares the Node test dependency in Rust CI. Quiet-machine performance measurements and reference comparisons remain separate O27 work; no new benchmark numbers are claimed.
