Add executable-agnostic real-world simulation monorepo testing in CI

[EladBezalel]

Summary

Add real-world simulation monorepo tests that run in CI for every pull request. The tests should be comprehensive and executable agnostic, such that we can run against old traf, domino, and possible future rewrite executables, comparing each outcome.

Details

• Develop a suite of simulation tests modeled on real-world scenarios.
• Ensure simulations are executable-agnostic, i.e., tests can be executed against traf, domino, and future binaries.
• Validate and compare outcomes between all executables against a common baseline, highlighting discrepancies.
• Integrate simulation runs into the CI workflow for every PR.
• Ensure tests are easy to extend for new executables or scenarios in the future.

Acceptance Criteria

• Real-world simulation suite is present in the monorepo.
• CI runs all simulation tests for every PR.
• Tests can run and compare multiple executables (traf, domino, etc.).
• Outcome differences are clearly reported in CI.
• Clear documentation on extending tests/executables.

Reviewed against origin/main (March 2026).

This issue is still relevant. The repository has regular integration tests and preview-release workflow coverage, but there is still no executable-agnostic simulation harness that runs the same real-world scenarios against multiple executables (for example, traf and domino) and reports diffs in CI.

I did not find any CI job or test suite that exercises this acceptance criterion yet, so this should remain open.
