As a user, I want to be able to view, join, and interact with channels on nounspace.

As a channel owner, I want to be able to customize the space for channels that I own.

AC:

1. All farcaster channels can be visited on nounspace via nounspace.com/c/[channel-name]
2. Users can search for and visit channels via Search
3. When a channel owner visits a space, they see the paintbrush and are able to customize the space

Out of scope:

1. Ability to create a new channel

2. Ability to channel owners to modify settings
