Fleet bootstrap – hybrid local+fleet
--------------------------------------------------
Every local Docker node spawned by a test is patched at start() time so
that it:

  1. Connects directly to node-01.do-ams3.waku.test.status.im:30303 as a
     static peer (TCP reachability confirmed via ``nc -vz``).
  2. Discovers all remaining waku.test fleet peers through the published ENR
     DNS tree (dns-discovery-url).

This makes each local nwaku container a genuine member of the live waku.test
network for the duration of the test.  Local nodes still relay test messages
among themselves (using their own cluster-id / shard topics), while fleet
nodes participate in peer-exchange and discv5 routing.

Fleet node information (addresses, peer IDs, ENR tree URL) is stored in
``src/env_vars.py`` (FLEET_NODES, FLEET_PRIMARY_MULTIADDR,
FLEET_DNS_DISCOVERY_URL)

Activation (opt-in, disabled by default):
  pytest <any-test-path> --fleet -v
  FLEET_BOOTSTRAP=true pytest <any-test-path> -v
