Add VELO to the asset registry

Aquarius is putting VELO up for community vote on its governance platform. VELO, issued by Velo Protocol, is a stablecoin backed by tokenized U.S. Treasury Bills as a Real World Asset. The asset has 24 billion tokens in circulation across 40,593 total trustlines and 23,087 funded trustlines, with a 7.3 rating on Stellar Expert as of July 21, 2026. Whitelisting VELO on Aquarius's asset registry would expand the liquidity layer's tradeable asset base and potentially unlock new market-making incentive pools.
