    .SYNOPSIS
        Extracts VM capabilities from a SKU object for compatibility and inventory analysis.
    .DESCRIPTION
        Parses the SKU's Capabilities array to find HyperVGenerations, CpuArchitectureType,
        temp disk size, accelerated networking, NVMe support, max data disks, max NICs,
        ephemeral OS disk support, Ultra SSD availability, uncached disk IOPS/throughput,
        encryption at host, and trusted launch status.
