Arjen e8270970ee feat(node): warm routes to direct peers at the mesh edge + app-owned DNS seam
A mesh-edge node (only direct BLE / Wi-Fi Aware / LAN peers, sparse bloom
filters) could not route to its own directly-connected neighbours: a
neighbour is never in another peer's bloom filter, so discovery was gated
off and find_next_hop had no coordinates. Traffic to such a peer failed
with "no route to destination" even with an established session.

- discovery: don't suppress a lookup on a bloom miss unless we have >2
  peers (trustworthy blooms); and when no tree peer advertises the target,
  flood the LookupRequest to every sendable peer — including the target
  itself, which answers a lookup for its own address, so the querier learns
  its coordinates and can route.
- session: when an established-session send hits no-route, trigger discovery
  (previously only session *initiation* did), so a coordless session — e.g.
  a platform-pushed peer whose Noise handshake came up before tree
  discovery — self-warms and the app's retransmit succeeds.
- node: add Node::enable_app_owned_dns() — returns the DnsIdentityTx an
  embedder (Android VpnService pump) uses to register identities it resolved
  itself, giving the same identity-cache/route-warming the built-in DNS
  responder provides.
