Add new XMTP channel extension for decentralized messaging:
- Direct messages (DMs) and group conversations
- Text messages, reactions, and attachments
- ENS address resolution for human-readable names
- Quantum-resistant encryption (MLS protocol)
- Multi-account support with per-account configuration
- Database isolation and network selection (dev/production)
- Comprehensive onboarding with wallet generation
Includes wallet generation scripts, example configurations,
troubleshooting guide, and test coverage for schemas, ENS
resolution, multi-account handling, and onboarding flows.
Note: Tests use Node's test runner format (node:test) and
should be converted to Vitest format in follow-up work.
Bug 1: Missing tag in channel list
- Changed selectionLabel from 'XMTP' to 'XMTP (Decentralized Messaging)'
- Updated both channel.ts and types.xmtp.ts to match package.json
Bug 2: allowFrom incorrectly required in pairing mode
- Removed forceAllowFrom condition from allowFrom prompt
- Now only prompts for allowFrom when dmPolicy === 'allowlist'
- Pairing mode correctly allows anyone to message (approved later)
