* [client] Extract peerRoutesAddr helper in toExcludedLazyPeers
Refactor: pull the AllowedIPs match into a named
peerRoutesAddr helper and document why forward-target peers are excluded
from lazy connections. No behavior change; the existing address match is
preserved as-is.
* [client] Add failing test for lazy-conn forward-target exclusion
toExcludedLazyPeers compares AllowedIPs (CIDR) against the unmasked
TranslatedAddress, so forward-target peers are never excluded. This test
asserts the peer is excluded and fails on the current behavior; the fix
follows.
* [client] Fix lazy-conn exclusion for ingress forward peers
peerRoutesAddr compared AllowedIPs (CIDR, e.g. a peer's overlay IP as /32)
against the unmasked TranslatedAddress string, so the match never fired and
forward-target peers were never excluded from lazy connections. Use prefix
containment so a routed address matches the peer's AllowedIP
* [client] Reuse parsed AllowedIPs from peerStore in lazy exclusion
Instead of re-parsing the network map AllowedIPs strings, look up the
already-parsed []netip.Prefix from peerStore.AllowedIPs (the same typed
value the lazy manager itself consumes). A down/lazy peer still has its
conn in the store, so exclusion is unaffected by connection state. Extract
a pure prefixesContain helper and unit-test it.
