dijkstra: V4 conformance test suite

[wolf31o2]

Summary

plutigo passes V1/V2/V3 conformance suites. Dijkstra introduces V4 with new builtins and cost model. plutigo must integrate the V4 conformance test suite once IOG publishes the test vectors.

What Needs to Happen

1. Track upstream IOG Plutus V4 conformance test vector release.
2. Add the V4 vectors to the existing conformance test runner.
3. Achieve 100% pass rate before Dingo can use plutigo for Dijkstra block validation.
4. Wire CI to fail on V4 conformance regressions.

Blocked By

• IOG V4 conformance test vector release

Downstream Consumers

• Dingo Dijkstra integration testing
