chore: Biome lint + coverage CI and frontend SEO/GEO#651
Merged
Conversation
CLI guardrails: - Add Biome 1.9.4 with a green-baseline config (recommended rules on, currently-violated stylistic rules disabled) so CI catches new issues without churning 85 existing files. Adds lint/format/format:check scripts. - Add test:coverage script (node --experimental-test-coverage) and wire Lint + coverage steps into the PR CI workflow. - Expand npm keywords for package discoverability. Frontend SEO/GEO: - Enrich root metadata: metadataBase, canonical, OpenGraph, Twitter card, robots directives, viewport, and SoftwareApplication JSON-LD. - Add robots.ts and sitemap.ts metadata routes. - Add public/llms.txt for generative-engine optimization. - Site origin is overridable via NEXT_PUBLIC_SITE_URL. Verified: biome lint clean, frontend tsc --noEmit clean. The 22 failing tests are pre-existing in this sandbox (env-specific) and unrelated.

What
Implements three of the repo-improvement suggestions: lint guardrails, test coverage in CI, and frontend SEO/GEO.
CLI guardrails
recommendedcorrectness/suspicious rules stay on, while the rules currently violated by the existing 85 files are disabled. This is a ratchet — CI catches new issues without a risky 85-file reformat in a live multi-agent repo.
