Fix adapters to follow the same template.

fix: restore adapter_build() contract, revert function renames

Both adapters now export adapter_build() and adapter_translate_*() as
the uniform public contract. scripts/build.sh sources one adapter and
calls adapter_build uniformly. Private helpers (_oc_*) and vocabulary
tables (cc_capability_to_tools, oc_capability_to_permission, etc.)
retain their prefixes. CC regression and OC unit tests all pass.
