vine: remove file from need to replicate if no replicas

[btovar]

If the replica count of a temp file is 0 because of workers disconnecting, we now remove the file from the "needs to replicate" table. This removes a warning when we try to reinstert the file into the table when the cache-update of the recovery task is received, and should make iterating the table a little more efficient.

The 'table' is a priority queue. Closing and looking for a more efficient solution.

I guess this isn't necessary? Because if the replica count of a file is 0, then the replication demand will be skipped when it is visited.

@JinZhou5042 It seems that this is fixed in master, but not the current release?

[JinZhou5042]

Yeah, I don't see this as a problem right now.

[btovar]

It is needed when it is a table and not a queue. Otherwise we get a debug message on reinsertion, like:
2026/01/20 14:07:06.48 vine_manager[1698412]error: Failed to insert key temp-rnd-jfglxpqaspvxfbq into hash table.

Ah got it!
