PR Summary

Low Risk
Low risk: changes are limited to updating example fixture data and expanding a regression test matrix to include Starknet v0.14.3; no production logic changes.

Overview
Updates the shared example_proof_facts.json fixture to use PROOF_VERSION_V1 (changing the first word from ...30 to ...31) and adds a pinned 0.14.3 copy under resources/regression_test/.

Extends regression_verify_proof_from_old_prover to run against the new 0.14.3 fixture so the verifier is continuously checked against proofs generated by that prover version.
