feat(block2): 'in your circle' trust — friend-of-a-friend, not a raw count

A network-wide 'N people vouch' count invites spam and means little. Now the
trust banner computes whether the peer is within YOUR circle — you vouch for
them, or someone you vouch for does (friend-of-a-friend) — via the pure
WebOfTrust rule (seeds={you}, threshold 1, distance 2). When known, the banner
turns green with 'In your circle' (else it falls back to the count).

The full member policy (threshold/distance/bootstrap) stays open (network-trust
§2); this is a deliberately loose 'people near you' heuristic.

Analyzer clean; trust cubit test adds a friend-of-a-friend vs stranger case
(run flutter test locally to confirm — the widget suite is too slow to run here).
