Drives all four seams over a real WebRTC room against a live livekit-server:
join under a minted token, gate each turn OUTSIDE the model (served vs refused
for unheld-capability / over-ceiling), meter the model calls, seal one
efficiency/1 that verifies under the steward key. examples/live_room.rs is the
runnable proof (data-plane turns → gate/meter/seal, receipt verified).
Clears two upstream blockers so `--features livekit` builds + runs on macOS:
- vendor/libwebrtc: libwebrtc 0.3.38 omits user_data that webrtc-sys 0.3.36
requires (broken upstream release pair); patched additively + [patch.crates-io].
- build.rs: emit -ObjC so libwebrtc's ObjC categories force-load, else
PeerConnectionFactory init crashes on an unrecognized selector.
Default build + tests are unaffected (the feature stays off by default).
