Public repo hygiene: scrub local identifiers from the design doc and the usage
examples/tests. docs/design-nested.md loses the hostname, the maintainer name, a
model name, and internal system/agent names (the rejected shared-store router is
now described generically, not by product name); its stale wire line is corrected
to netstring(argc) while there. Usage comments and test fixtures switch real fleet
hostnames/container names to host1/host2/app/db. No behaviour change; all tests green.
