and already even mobile phones have 64-bit CPUs
Is it correct to place already there?
and even mobile phones already have 64-bit CPUs
feels better to me.

Both are fine and you could even put it at the end. Check out this Cambridge dictionary page about it.

trivially_copy_pass_by_refto 16 bytes, which is the number of bytes that fit into two 64-bit CPU registers.The default clippy value for this is 8 bytes, which is chosen to improve performance on 32-bit. Given that druid is being designed for the future and already even mobile phones have 64-bit CPUs, it makes sense to optimize for 64-bit and accept the performance hits on 32-bit.
This also changes command
Targetto be passed by value. It's a breaking change, but given that commands are getting redone in #908 anyway, I think this is about as perfect of a time to change this as possible.
