Updates the "Quick links the reviewer should bookmark" section of
doc/reviewer/README.md so it matches the Pages-hub v4 layout:
* the hub itself now carries status badges, a "what's new" banner,
and the research-alignment table — call this out so the reader
knows what to expect when they click through;
* adds direct links to the three documents that the new Q1/Q2/Q3
questions actually depend on (references.md, phases.md,
research-track.md) — previously only the Schläfli-derivation note
and the locked-vs-flexible architecture page were linked;
* re-points the Schläfli derivation link from "Q2" (old numbering)
to "Q3" (new numbering after baustein B inserted research
questions at Q1/Q2).
Companion change to the Pages-hub v4 already pushed to the codeberg
`pages` branch; this commit keeps the in-repo guidance in sync.
