PR Summary

Low Risk
Changes are regression tests and versioned-constants snapshots for OS resource accounting; no production execution-path logic beyond updated fee constants.

Overview
Extends the OS execute_txs_inner resource regression test so it measures declare transactions alongside invoke, not invoke alone.

The test runs a minimal declare using a fixed data-gas account class (unchanged artifacts for stable numbers), subtracts blockifier business-logic resources from full OS trace resources, and writes the remaining constant declare overhead into blockifier_versioned_constants_0_14_4.json (e.g. 3938 steps, 92 range-check builtins vs the previous 3523 / 72).

The deployable-for-resource-measurement account contract gains a stub __validate_declare__ entry point with matching CASM/Sierra updates so validation paths stay consistent. Minor formatting-only edits appear in the OS resources test Cairo source.
