refactor: open GroupListViewer via chat command with kind 10009 naddr

Instead of a separate 'chats' command, open the multi-room group list
interface by passing a kind 10009 naddr to the chat command.

Changes:
- Fix TypeScript error in GroupListViewer (replaceable returns single event)
- Add GroupListIdentifier type for kind 10009 addresses
- Update chat parser to detect kind 10009 naddr and route to GroupListViewer
- Update WindowRenderer to check identifier type and render GroupListViewer
- Remove 'chats' command and appId (consolidated into chat command)
- Update chat command documentation to include kind 10009 example

Usage:
  chat naddr1...10009...    Open multi-room group list interface
