ERC-8172: Delayed Metadata Update Extension

Hi all,

This is the discussion thread for ERC-8172, an optional extension to ERC-8004 that adds a delayed metadata update mechanism.

The problem: once an agent passes verification, nothing stops it from instantly swapping its endpoint or configuration. This extension introduces a cooldown period before URI changes take effect, giving monitoring systems and users time to react.

New functions: setAgentURIWithCooldown, applyPendingChange, cancelPendingChange New events: PendingURIChange, PendingURICancelled

Fully optional, backward-compatible with ERC-8004.

PR: https://github.com/ethereum/ERCs/pull/1561

Happy to discuss cooldown duration, security trade-offs, or anything else.
