Allow for nonprofit development and management of attainable workforce housing on state lands

This bill amends Montana law to clarify that nonprofit organizations can develop and manage "attainable workforce housing" on state trust lands through commercial leases. It updates the definition of "commercial purpose" to explicitly include nonprofit residential development for working-class housing, such as single-family or multifamily projects under a master lease. The change allows nonprofits to lease state lands for this specific housing purpose, while excluding agriculture, grazing, oil/gas development, and individual home sites. This is a technical clarification of existing leasing rules, not a new housing program, directly affecting nonprofits seeking to build affordable housing on state lands.
