GET /api/viral-videos/channel-ideas

What to make next for a channel, taken from the channels most like it. Resolves the channel, finds the closest channels by what they cover, reads what actually worked on them, groups the same topic (or the same title shape) written different ways, and removes what this channel has already made. Ranked by how many separate channels made an idea work, not by raw views, so a big channel covering something does not crowd out a real idea.

Read hits against videos: 2 hits in 5 tries is a crowded topic where most attempts sink; 3 hits on 3 channels is one that travels. A 422 with "code": "not_enough" means the channel resolved but too little is held behind it to say anything honest. It is not an error; show the reason rather than an empty list.
