```
tmux.Server.SetUserKeys(ctx: context.Context, value: SparseArray[string]) -> (SetArrayResult, error)
```

SetUserKeys replaces the complete "user-keys" server option array with SparseArray[string], preserving holes and empty values (tmux 3.2a or later). Read it with [ServerOptionValues.UserKeys] from [Server.Options]; [Server.UnsetOption] restores inheritance or the global default. Replacement is not atomic: the result reports confirmed writes, and failures stop without rollback. Serialize concurrent replacement of the same target and option.
