feat(library): add a speedrun mood from speedrun.com

The picker takes mood=SPEEDRUN for backlog games with a speedrun.com
game that has at least one verified run. The game detail returns the
link as speedrunUrl.

speedrun.com has no Steam or IGDB link, so games are matched by name
and, when IGDB knows it, by release year (one year off at most). One
queue serves all users at 1 request per second. Results are kept 30
days in game_speedrun.
