MetadataHub doesn't send changes for beatmaps entering (or leaving) a graveyarded state

[peppy]

As mentioned in ppy/osu#23159

Currently we are only conveying change information when a user is responsible for making a change to a beatmap. Eventually we'll want to change this to also include automated (or manual) changes to beatmap status which aren't triggered by a BSS change.

Relevant code:

osu-server-spectator/osu.Server.Spectator/Database/DatabaseAccess.cs

Lines 271 to 289 in 08bfe2a

	public async Task<BeatmapUpdates> GetUpdatedBeatmapSets(int? lastQueueId, int limit = 50)
	{
	var connection = await getConnectionAsync();
	if (lastQueueId.HasValue)
	{
	var items = (await connection.QueryAsync<bss_process_queue_item>("SELECT * FROM bss_process_queue WHERE status = 2 AND queue_id > @lastQueueId LIMIT @limit", new
	{
	lastQueueId,
	limit
	})).ToArray();
	return new BeatmapUpdates(items.Select(i => i.beatmapset_id).ToArray(), items.LastOrDefault()?.queue_id ?? lastQueueId.Value);
	}
	var lastEntry = await connection.QueryFirstOrDefaultAsync<bss_process_queue_item>("SELECT * FROM bss_process_queue WHERE status = 2 ORDER BY queue_id DESC LIMIT 1");
	return new BeatmapUpdates(Array.Empty<int>(), lastEntry?.queue_id ?? 0);
	}
