docs-validation: expand curated markdown scope to include all documentation hubs

Add all documentation subdirectories to the curated markdown linting targets, replacing the previous exclusion-based approach with comprehensive coverage. Update validation to check for required README files across all hubs and verify priority documentation metadata markers. Implement lazy loading for optional dependencies (numpy, redis, bcrypt, jwt, websockets) in agent-coordinator and related modules to improve startup
