.env.example still described the #896 model: the ingestor owning an RNS
identity and deriving its !xxxxxxxx from "the transport identity already
in RETICULUM_CONFIG_DIR". #897 shipped the opposite. RE8 excludes the
transport identity from the pick, because RNS generates it as an
independent keypair that matches none of the operator's announced
destinations; the id is the discovered primary identity, the one
announcing the most destinations on the machine. README says this
correctly and .env.example contradicted it, pointing operators at the
hash rnstatus prints as "Transport Instance".
The strands-the-old-row caveat #897 added to README and CHANGELOG is
carried over too, since .env.example is where an operator is standing
when they set the variable that moves the id.
Two guards in the deployment-surface class, both negative-tested against
main, where they correctly fail.
pytest 1443 passed; black clean.
