PR Summary

Low Risk
Test-only changes to syscall trace parsing and assertions; no production fee or OS resource logic is modified.

Overview
OS resources regression testing now strips the full fee-transfer syscall tail (10 selectors: execution info, storage reads/writes, emit event) instead of only dropping a single trailing EmitEvent.

A pinned FEE_TRANSFER_SYSCALLS list documents that tail, and a new test_fee_transfer_syscalls runs a no-op __execute__ invoke so every traced syscall should come from fee transfer only. The regression test **split_at**s those syscalls off before measuring __execute__ costs, asserts the tail matches the constant, and fails if any measurable syscalls remain after the loop.

const SYSCALLS_WITH_LINEAR_FACTOR: [Selector; 2] = [Selector::Deploy, Selector::MetaTxV0];

/// Expected syscalls in the fee transfer call. Should be removed from the list of syscalls during

You can run this tx with trivial fee bounds and make this test a bit cleaner
