PLAN.md calls out "Broadcast traffic flowing" as a user-facing diagnostic.
The tunnel stats only reported total Ethernet frame counts, so the client
could not distinguish whether broadcast traffic was actually crossing the
tunnel.
Add defaulted broadcast tx/rx counters to TunnelStats while preserving the
existing constructor and old JSON compatibility. Client and gateway accounting
now increments those counters from validated Ethernet frames, and the client
diagnostics line reports the broadcast flow next to total frame counts.
Relay peer stats logs include the new counters so operators can see broadcast
activity from forwarded stats snapshots too.
Test Plan:
- cargo fmt --check
- cargo test -p lanparty-obs -p lanparty-client-core -p lanparty-gateway \
-p lanparty-client-win -p lanparty-relay
- cargo test --workspace
- cargo clippy --workspace --all-targets -- -D warnings
- git diff --check

Add the observability vocabulary needed for phase-1 frame logging and client
status reporting. Runtime crates can now emit structured events without each
binary inventing separate field names for the same tunnel state.
The new models cover frame direction, action, drop reason, parsed Ethernet frame
logs, malformed frame logs, tunnel counters, relay/QUIC/TAP client diagnostics,
and user-facing diagnostic messages. TunnelStats now lives in lanparty-obs and
is re-exported by lanparty-ctrl so stats remain one shared type whether they are
logged locally or carried over the control stream.
This still does not add logging sinks or tracing integration; those should be
wired in when the relay, gateway, and client loops exist.
