PR Summary

Medium Risk
Touches protocol-facing OS gas constants, allowed virtual OS hashes, and program hashes used for proving compatibility; changes are driven by remeasured syscall costs but affect fee and validation expectations.

Overview
Adds secp256k1 and secp256r1 syscall coverage to the OS resources measurement harness so their VM step costs are captured by the regression test instead of being skipped.

The Cairo OsResourcesTestContract now exercises all ten secp syscalls in __execute__, with fixed curve constants. os_resources_test drops those selectors from UNMEASURABLE_SYSCALLS and allows Secp256k1New / Secp256r1New to appear twice in traces (second visit ignored). Measured n_steps and matching OS gas constants for secp syscalls are lowered slightly; blockifier_versioned_constants_0_14.4.json, constants.cairo, program_hash.json, and the 0.14.3→0.14.4 diff file are updated accordingly, including a new allowed virtual OS program hash and refreshed OS / virtual_os hashes.
