Adds a hang-interop job that runs after lint and exercises the
:nestsClient:jvmTest suite under -DnestsHangInterop=true. Cargo
registry + cli/hang-interop/target are cached on the
Cargo.lock + REV file hashes so cold runs (~6 min for the
moq-relay install) only happen on dependency change; warm runs
finish in seconds.
Linux-only — the protocol logic is platform-agnostic and the
JNA libopus natives are already exercised by JvmOpusRoundTripTest
on the Android job. macOS / Windows interop runs would double
the matrix cost without catching new defects.
Pinned to dtolnay/rust-toolchain@stable; ubuntu-latest's bundled
Rust drifts and moq-relay 0.10.25 needs ≥ 1.95 (the
constant_time_eq 0.4.3 transitive dep).
