Quality standards and guardrails

Problem

As more contributors add extension features — new panel types, diagnostic rules, MCP tool integrations, preview capabilities — there are no enforced quality standards governing how these surfaces behave. One contributor's panel may handle errors gracefully while another silently swallows them. Diagnostic messages vary in tone, specificity, and actionability. Preview rendering for new chart types may ship without loading/error states. Without defined standards and automated guardrails (linting rules, review checklists, integration test requirements), the extension's quality becomes inconsistent and degrades as the contributor base grows, creating a patchwork experience that undermines user trust.
