What

Several README links point to missing pages under docs/guides/ (build guide, troubleshooting, performance tuning). Create these pages so the README becomes navigable.

• Current: Broken internal links in README.md
• Expected: All referenced guides exist and render
• Scope: docs/guides/BUILD.md, docs/guides/TROUBLESHOOTING.md, docs/guides/PERFORMANCE.md

Why

• Broken links signal an unmaintained project to new users
• First-touch developers need a build guide in one place

How

Technical Approach

1. Audit README with markdown-link-check in CI
2. Populate missing pages, referencing existing README snippets
3. Add link-check.yml workflow

Acceptance Criteria

• Zero broken links in README.md
• markdown-link-check runs in CI
• Three guides exist with examples
