fix(array-merge): route mixed-key merges through faithful array_merge

* Config::merge called array_merge_recursive where PHP uses plain
  array_merge (string-key overwrite); switch those six sites to
  array_merge.
* provides/replaces merges that may carry an AliasPackage's
  self.version numeric keys ("0","1",...) were collapsing under naive
  chain/insert/or_insert; route them through a new array_merge_map().
