nook: render the full release history on /changelog

The appcast retains only recent items, so releases before 0.6.0 had no
surface. The five older sections (0.5.0 back to the first widely
distributed 0.2.0) were recovered from the changelog file's git
history (The-Nook 1ad8a69 / db165cd), converted to the same HTML the
embed step produces, and checked in as an archive the page merges
behind the appcast items — appcast stays authoritative, archive fills
the gaps. 0.3.1 and 0.6.1 shipped without written notes and are absent
by design. Also fixes the accordion snapping 0.6.3 back open when all
sections were collapsed: after any click the state is a version or an
explicit none sentinel, never the initial first-open default.

Tests: tsc clean; dev render shows all eight releases with notes in
the DOM.

Issue: FRE-13
