PLAN.md calls for heavy diagnostics and better malformed-frame handling. The
relay already disconnected peers after repeated malformed datagrams, but overlay
or header-level malformed datagrams had no operator-facing count until the peer
was closed.
Log each malformed peer datagram with room, peer id, role, current count,
threshold, and whether the threshold is disconnecting the peer. Keep the
existing threshold behavior unchanged; this only makes the counter visible.
Document the malformed-datagram count in the relay README section.
Test Plan:
- cargo fmt --check
- cargo test -p lanparty-relay
- cargo test --workspace
- cargo clippy --workspace --all-targets -- -D warnings
- git diff --check
