- GET /games/me/active and /games/me (Bearer token), /games/popular (live
games, or the most spectated finished ones), and /game/:id now also
returns saved records of finished games
- Lists are cached in Valkey for 10 seconds, cleared when a game is saved,
and empty instead of failing while the database is down
- Live game previews over WebSocket: subscribers get the top 5 on
subscribe and on change, at most once per second, without counting as
spectators; ids are public ids
- RTMT supports several connection listeners
- Spectators are removed from games when they disconnect; the lookup
iterated an iterator with for...in and never found anything
- Finished and left games are removed from memory, not only from the
player mappings
- The connection info is sent once when a game starts
