Pass --allow-dirs=evals to skill-validator so the internal-tooling evals/
subdirectory under each skill no longer trips the spec's "unknown directory"
warning. The agentskills.io spec explicitly permits additional directories
at the skill root; the eval suite layout lives under evals/<suite>/ and is
read by this repo's eval runner only, not by agents at runtime.
