RelayUntrusted

An untrusted relay never beats a trusted link with the same hardware

Test	What it does	Result
test_relay_ceiling	Every PURE-LOSS relay configuration sits under -log2(1 - T); a helping correlation donates entanglement and is not repeaterless-bounded.	✅ pass
test_relay_hardware	Worse efficiency, more dark counts and worse mode match each raise relay_error.	✅ pass
test_relay_matches	With the encoder's arm lossless the relay rate equals the trusted-heterodyne rate over the surviving arm to 1e-4.	✅ pass
