A route now consumed with two hosts when the mesh composed both — the
same host under internal-name reaches the same rule as its public name,
restoring the convenience a predecessor proxy gave for reaching a service
over the VPN without a public TLS round trip (the field composeName now
writes, feat/route-carries-internal-alias — this branch depends on that
one landing for internal-name to ever be populated; builds and tests
clean without it, just serves nothing extra).
Never certified: onlyWhatTheMeshSaid used routed(), which answered yes
for any host in the table regardless of how it got there. A new
eligibleForACME() checks a parallel 'public' set instead — every host
reached through a route's own name, never one reached only through its
internal-name — so an internal alias is proxied but never given its own
failing ACME order. routed() is unchanged and still used for the 404
message, which legitimately wants 'is this host served at all.'
