History and recovery, per namespace

The namespace is the part of the channel name before the colon, and it decides everything about what a reconnect can recover.

Namespace	History	Retention window	Client `history()`
`orderbook_v3`	1	6 h	No
`orderbook_v3_event`	100	5 min	Yes
`account`	100	5 min	Yes
`recent_trades_v3`	100	5 min	Yes
`markets`	1,000	5 min	Yes
`main_line`	500	5 min	Yes
`fixtures`	100	5 min	Yes
`best_odds_v3` · `parlay_markets`	None	—	—

History is bounded by both the message limit and the retention window, whichever is reached first. A publication is only recoverable while it is still within the retention window and has not been pushed out by newer messages once the limit is hit.
