565f8cfb7a *: fix copyloopvar warnings 
Go 1.22+ allows to drop these:

  The copy of the 'for' variable "i" can be deleted (Go 1.22+) (copyloopvar)

1b83dc2476 *: improve for loop syntax 
Mostly it's about Go 1.22+ syntax with ranging over integers, but it also
prefers ranging over slices where possible (it makes code a little better to
read).

Notice that we have a number of dangerous loops where slices are mutated
during loop execution, many of these can't be converted since we need proper
length evalutation at every iteration.

5431b31d84 core: fix extensible sender check

sort.Search can return an index that is not equal to the target.
slices.BinarySearchFunc can do that too, but it also return a very convenient
boolean status that can be used.
