test: add validation harness for emitted outputs
Structural validators for Schema.org JSON-LD and A2A agent cards, a naive regex-based pipeline for AST necessity comparison, and competitor scraping against Mintlify-powered sites. Results written to validation/ as JSON for downstream analysis. Co-Authored-By: Claude <noreply@anthropic.com>
