ruflo-metaharness

ruflo-metaharness surfaces MetaHarness CLI tools (score, genome, threat modeling, security scanning, harness scaffolding, and evolutionary mutation) through 13 ruflo skills, maintaining optional pluggability so ruflo remains fully operational if MetaHarness packages are removed. All skills degrade gracefully on missing dependencies, use subprocess invocation with structured JSON output, and enforce security controls via a mod function-hook that blocks secrets in inputs and gates privileged operations.
