Founder-level Token Vesting

This is a proposal to continue our token vesting program for founder-level contributors to the DAO, at the same rate of 2.5% per year for up to 4 years with a 1 year cliff. You can read more background here: https://forum.cabin.city/t/token-vesting-proposal/139

This proposal would result in two token grants:

1. Jon Hillis - 2 more years of time locked tokens @ 2.5% of supply per year (25,000 ₡), vested based on continued work for the DAO since the end of the previously approved proposal, which covered the first two years

2. Alex Grintsvayg - 4 years of time locked tokens @ 2.5% of supply per year (25,000 ₡), vested based on continued work for the DAO with a 1 year cliff, starting 1/1/24
