The "unread" file contains unread messages from the corresponding channel.
The message display format is:
DateTime <ThreadId> Username: Message
The "in" file can be written to to post messages to the channel.
The code does not sync state. For example, if you're added to a new team or join a new channel,
you'll need to remount the filesystem to see these changes. Support for live syncing of state is planned.
The code is in alpha. There will be breaking changes.
