Implement Plutus Conformance Tests for Scalus UPLC JIT Compiler

Type: Feature / Enhancement
Topic: Testing, Performance, JIT

Problem Description

The scalus-uplc-jit-compiler is currently experimental and lacks validation against the official Plutus conformance test suite. As noted in scalus-uplc-jit-compiler/test-notes.md:

No dedicated unit tests are added for case on builtins in the JIT compiler because:

1. The Plutus conformance tests will be run against the JIT compiler in the future

Without these tests, we cannot guarantee the JIT compiler matches the reference CEK machine behavior, especially for edge cases and gas usage.

Proposed Solution

Extend PlutusConformanceTest to support the JIT compiler backend.

Action Items

• Create a new test class JitPlutusConformanceTest in scalus-uplc-jit-compiler/src/test/scala.
• Implement the check method to invoke the JIT compiler instead of the CEK machine.
• Run the suite against standard Plutus conformance vectors.
• Document discrepancies or failures.

Value Add

• Reliability: Proves correctness of the JIT compiler.
• Maturity: Essential step for moving JIT from experimental to production.
