v0.33.3 — Hall of Fame sweep is capacity-based, not age-based

Fixed

• Unfinished runs stayed on the board instead of being swept a day after your last move. The board's cleanup previously deleted any in-progress run once it was more than 24 hours old — and since finishing the game is rare, nearly every run is "in progress," so the whole board would empty out roughly a day after each play session. In-progress runs are no longer removed on age alone; they stay until the board holds more than 20 of them, and even then only the oldest excess ones, older than 30 days, are cleared out. Finished runs were never affected and still stay forever.
