CIP-0035: Add Five North as a Tier2 SV (Weight 3)

CIP 0035 proposes adding Five North (5N) as a Tier2 SV with a weight of 3, contingent on 5N committing 90% of its SV earnings to invest in Canton Network applications. This mechanism establishes an ecosystem fund where 5N, acting as a venture capital entity, will distribute venture earnings (minus fees) back to the GSF for reinvestment. The proposal aims to foster ecosystem growth through equity investments rather than grants, providing a sustainable, return-generating model for community benefit.
