Read-only skill: given a topic, resolve it to an anchor page via the
cascade, walk the graph edges (2 hops, ~8-page cap) — falling back to
link-following when no edges exist — order the pages pedagogically
(prerequisites first, then the topic, then what builds on it), and print
a numbered reading tour with per-page "what you'll find" notes.
