"""mumble — protocol integration parity port (Phase 2 P2 + §4.3 recipe-specific depth).

SOURCE: recipe-info/mumble/tests/mumble_connect.py — "connects via TLS, authenticates, verifies
server version, channel list, welcome text, and ServerSync handshake. Zero external dependencies."

This is mumble's characteristic "is it really working" check: the voice server has no HTTP API, so
the meaningful liveness/behaviour proof is the control-channel handshake — a TLS connection that is
ACCEPTED (anonymous auth, no Reject), receives the server Version, sees the root channel
(channel presence — §4.3 "channel presence beyond TCP health"), and completes with ServerSync.
