Generally revise procurement laws

This bill revises Montana's state procurement laws by updating definitions and clarifying how public funds are spent on contracts. It directly affects state government departments, purchasing agencies, and vendors who supply goods or services to the state. Key changes include redefining terms like "procurement," "contract," and "services" to ensure clearer application across different types of state agreements. The bill also clarifies that grants from the federal government are treated differently from standard procurement contracts and establishes which state entities fall under these new rules.
