0.8.0

Changed

• Lesson numbering aligned across the repo. The six planned framework-tour outlines moved from the
  repo root into roadmap/ and were renumbered to their curriculum numbers — LangChain 3→7,
  LangGraph 4→8, Ollama 5→9, Semantic Kernel 6→10, Bedrock 7→11, Google ADK 8→12. Every
  written guide's navigation chain, cross-references, and "next lesson" links now follow the real order
  (1 RAG → 2 MCP → 3 Hybrid → 4 Safety → 5 Eval → 6 Repo → 7–12 framework tour), so the live Lessons
  3–5 are reachable from the guides instead of being shadowed by the old outlines.
• PDF build (tools/build_lesson_pdfs.py): emits LESSON7–12.pdf from the roadmap/ sources under
  their curriculum numbers, while LESSON3–5.pdf are now built from the live lesson READMEs; the stale
  outline-based PDFs under the old 3–6 numbering were dropped. The builder now auto-discovers
  lessons from disk (root LESSON<n>.md, lessons/<NN>-slug/README.md, roadmap/LESSON<n>-slug.md), so
  a new lesson gets a PDF with no edits.
• Home page lists every lesson PDF through two dropdowns (Lessons 1–5, Roadmap 7–12) instead of a
  single Lesson-1 link.

Added

• roadmap/README.md: an index of the planned-lesson outlines that points back to where the live
  lessons live.
• Educator positioning — a README "About the author" + "What you'll be able to do" section, a
  "Who's teaching this" section on the site home, an "About the author" section on docs/about.html,
  and a new SYLLABUS.md (clusters, per-lesson learning objectives, prerequisites matrix, and time
  estimates).
• Printable PDFs for the live Lessons 3–5 (built from each lesson's README.md) — docs/pdf/ now
  covers Lessons 1–5 and 7–12.
• Auto-generated README "Lessons & downloads" table via tools/sync-readme-downloads.py, listing
  every lesson's Markdown guide and PDF plus the guide PDFs; --check mode fails CI when it's stale.
• Cookieless usage analytics (docs/assets/analytics.js): privacy-friendly GoatCounter that loads
  on the production site only, over HTTPS, scoped to the /local-ai-lab/ path, with queued early events
  and lightweight click/slide tracking. Wired into every docs/*.html page.
• AI-for-developers cheat-sheet — a printable docs/pdf/CHEATSHEET.pdf plus a nav link in the
  generated lesson pages; the About page now links the related NikOS and leak-lock projects.

Fixed

• Hardened the PDF asset resolver (tools/build_lesson_pdfs.py): _resolve_asset now rejects
  remote URIs and out-of-tree absolute paths, so the build can't pull in assets outside the repo.
