Reduce stkTRU cooldown period

Summary

This proposal seeks to reduce the stkTRU cooldown period from 14 days to 2 days.

Rationale

This proposal seeks to increase governance participation by reducing friction to staking TRU.

stkTRU serves a key role in on-chain governance and management of TrueFi smart contract infrastructure (approving new managers, setting fees, etc.). This proposal would bring stkTRU parameters in line with TrueFi governance parameters, where on-chain proposals have a 2-day delay period before voting commences.
