Add Homework 2 summary and a navigation sidebar - Home.md: add a Homework 2 section (what I built, what I learned, more detail) mirroring the existing Homework 1 structure; make the repeated "What I learned"/"More detail" headings unique per homework and add explicit HTML anchors so links resolve reliably. - _Sidebar.md: add a custom sidebar linking to each section via its anchor, replacing the default single-page listing.
Add course journey, links, and Homework 1 learnings
