Mesh/federation messages between co-located nodes were always falling back to
Tor because the FIPS overlay had no direct peering — every node depended on the
global anchor's spanning tree, and when that anchor link flaps a node is
isolated and all FIPS dials time out. (Diagnosed live on .116/.198: pure-FIPS
direct peering over UDP 8668 fixes it — 2.5ms vs timeout.)
Generalize the manual fix: in the existing 5-min FIPS seed-anchor apply loop,
also auto-connect every federation peer the PeerRegistry knows both a LAN
address AND a FIPS npub for, dialing its FIPS UDP transport (port 8668) at its
LAN IP via the same idempotent `fipsctl connect` path (new
anchors::lan_fips_anchors). This is FIPS's own transport over the LAN — NOT
Tailscale, NOT the HTTP/LAN messaging port. Transient (recomputed each tick from
live mDNS discovery, never persisted) so changing IPs self-correct. Remote peers
with no LAN address are untouched (still routed via the anchor).
Registry Arc hoisted out of the transport-init block so the loop can read
all_peers(). cargo check green.
