Generally revise Montana SNAP program laws

This bill would allow Montana's SNAP program to request federal waivers to restrict purchases to healthy foods like fruits, vegetables, and protein, and to limit EBT card use for household food purchases to individuals over 16. It also establishes a transitional benefits program that gradually reduces SNAP benefits as household income rises above 138% of the federal poverty level, with benefit amounts decreasing from 100% to 20% across five income tiers. The legislation includes reporting requirements for the department to track waiver status and spending patterns, updates legal terminology, and amends existing state laws related to SNAP funding and benefit administration.
