[Proposal] Dreamline as on-chain policy layer for AEON x402 on BSC

[aisatoshinext-arch]

AEON solves how agents pay on BNB Chain.
Dreamline solves whether they should.

We've integrated Dreamline as a policy layer that sits in front of the AEON facilitator:

1. Agent calls POST /facilitator/verify (Dreamline)
   → checks on-chain blacklist on BNB Chain (DreamlineRegistry)
   → checks agent policy (budget, whitelist)

2. If approved → POST /facilitator/settle (Dreamline)
   → routes to AEON facilitator for BSC mainnet settlement

Dreamline's /facilitator/supported now explicitly lists AEON as the
settlement layer for BSC:

{ "network": "bsc", "facilitator": "AEON" }
{ "network": "eip155:56", "facilitator": "AEON" }

The trust anchor (blacklist) lives on BNB Chain — not on a server.
No server compromise can override a blocked destination.
