Expand description

Handle an incoming subtree audit challenge (responder side).

Validates the challenge targets this node, looks up the pinned commitment in the retained (last-two-gossiped) set, and builds the subtree proof for the nonce-selected branch. If this node is bootstrapping it says so; if it genuinely does not retain the pinned commitment it rejects (which the auditor treats as a confirmed failure for a recently gossiped root).
