🟢cheapest_routes(from, to, max_price, month, limit)
The cheapest cached fare on every route we hold from an origin (or into a destination), cheapest one-way first, each with its cheapest round trip of a 3 to 21 day stay in `return` when we hold one. Filter by a maximum price and a departure month here rather than by reading the list; both apply to the one-way. Prices are one adult, economy, as last seen on the date in `checked` — observations, not quotes.

Everything we hold for one airport pair: the cheapest one-way, the cheapest round trip of a 3 to 21 day stay, the cheapest one-way by departure date and by month, and the cheapest round trips. If we hold nothing yet, it starts pricing the route and says so; ask again a minute later.
