PR Summary

Low Risk
Test and versioned-constant snapshot updates driven by OS resource measurement; no production execution-path logic changes.

Overview
Extends test_execute_txs_inner_resources to run a third Declare transaction (using the stable DATA_GAS_ACCOUNT class) and record the OS-only overhead under execute_txs_inner.Declare.

Versioned constants for 0.14.4 are updated with the measured Declare scaffolding cost (3938 steps, 92 range-check builtins, plus pedersen/poseidon), and the 0.14.3→0.14.4 diff regression file picks up those lines.

Supporting fixture churn: the resource-measurement deployable account gains __validate_declare__ with refreshed Sierra/CASM artifacts; the OS resources test contract uses deploy salt 3 for deterministic deploy syscall costs; central systest blob/preconfirmed JSON values shift from regenerated runs.

crates/blockifier_test_utils/resources/feature_contracts/cairo1/os_resources_test_contract.cairo line 107 at r1 (raw file):

        deploy_syscall(stable_class_hash, 3, array![0].span(), true).unwrap_syscall();
        // linear factor (calldata len = 1):
        deploy_syscall(stable_class_hash, 3, array![1, 0].span(), true).unwrap_syscall();

the stable contract changed, so the magic salt that hits the same Deploy resources must also change

Code quote:

        deploy_syscall(stable_class_hash, 3, array![0].span(), true).unwrap_syscall();
        // linear factor (calldata len = 1):
        deploy_syscall(stable_class_hash, 3, array![1, 0].span(), true).unwrap_syscall();
