Add iMessage Channel

Adds iMessage support via the Chat SDK bridge. Two modes: local (macOS with Full Disk Access) or remote (Photon API).

Install

NanoClaw doesn't ship channels in trunk. This skill copies the iMessage adapter in from the channels branch.

Pre-flight (idempotent)

Skip to Credentials if all of these are already in place:

• src/channels/imessage.ts exists
• src/channels/index.ts contains import './imessage.js';
• chat-adapter-imessage is listed in package.json dependencies

Otherwise continue. Every step below is safe to re-run.

1. Fetch the channels branch
