[Feature] Implement POCW Consensus Mechanism for Ordinary Transfers

[ivan-xin]

Design and implement a POCW consensus mechanism specifically optimized for ordinary transfer transactions.

Start with algorithm design - Before coding, clearly document the POCW algorithm in a markdown file
Incremental integration - Add POCW as a parallel path, don't modify existing consensus initially
Feature flag - Use POCWConfig::enabled to toggle POCW on/off
Consider future POA/POR - Design with extensibility in mind for the other consensus types

Hi @ivan-xin ,

Thanks for explaining the issue.

I have done a lot of due diligence on algo deisgn here and have come up with the following design.

In here you will find how ordinary transfers are not PoCW worthy and could have a slight different anchoring mechanism from Task based transfers. But as you have planned, they can be a part of the same event DAG.

Let me know if you like the design, and then I can code it in the repo.
