A missing apktool launcher projected the generic "unavailable for the
current target" message and remediation, leaving the actual reason only
in details.reason. A relative REA_APKTOOL_COMMAND escaped as UNKNOWN
because command selection ran before the try that maps configuration
failures.
Resolve the selection inside that try for both execution and
availability, and pass the refusal reason as userMessage, as JADX and
the adapters fixed in #1224 do.
