PR Summary

Medium Risk
Updates syscall gas and OS resource tables used for fee accounting and client-side proving allowlists; incorrect values would misprice transactions or reject valid proofs.

Overview
Extends the OS resources measurement harness so __execute__ on OsResourcesTestContract also exercises get_block_hash, get_class_hash_at, and get_execution_info_v2, and drops those selectors from the “unmeasurable” list in test_os_resources_regression.

Measured OS step/builtin costs for GetBlockHash, GetClassHashAt, and GetExecutionInfo are updated in blockifier_versioned_constants_0_14_4.json, with matching syscall gas constants in Cairo constants.cairo. OS / virtual OS program hashes (program_hash.json, allowed virtual OS list, and the 0.14.3→0.14.4 diff snapshot) are refreshed to match the rebuilt OS artifact.

        // get execution info syscall.
        get_execution_info_v2_syscall().unwrap_syscall();

Same OS impl though

Suggestion:

get_execution_info_v3_syscall()
