Outgoing voice was gated on the observer's roster copy of the remote user's
voice state, which is signaling gossip. The signal server broadcasts
`user_left` for any socket it declares dead, so a suspended laptop or a flaky
hop wiped that copy and the observer detached its microphone from a peer that
never left the channel - a silent member with no way back through the UI.
`decideVoicePathRouting` now closes a path only on positive evidence: we left
voice, the peer itself reported another channel or none, or the connection is
gone. Missing gossip holds an established path instead. Opening still needs
confirmation, so a guess never starts sending; the same rule gates playback,
camera video, and the microphone a new connection puts in its first offer.
Peers are also asked for their voice state when a connection or data channel
comes up, so a rebuilt path re-confirms itself.
Alongside it, the microphone can be switched mid-call: capture moves to a
device service and rules, the live track is swapped with `replaceTrack` so
the session is never renegotiated, and the speaking indicator follows the new
stream.
Peer recovery burned its whole retry budget while signaling was down, then
dropped the tracker with no re-arm, so a peer stayed dead until an unrelated
roster event healed it. Recovery now waits for a usable transport before
spending an attempt.
Initiator election also compared a home actor id against foreign roster ids,
which is not antisymmetric across signal servers - both sides offered, or
neither did. Election moves into `peer-role.rules` and compares ids only
within one signal server's identity space.
Match incoming direct-call events against every local identity alias - home
id, entity id, peer id, and each provisioned signal-server actor id - instead
of only oderId||id. A caller who met the callee through a room on the
caller's signal server addresses the ring by the callee's provisioned actor
id, so the old admission check silently dropped it: the caller went "In
Voice" while the callee saw no modal, no ring audio, and no rail entry.
Incoming self aliases are normalized onto the canonical local id
(normalizeDirectCallPayloadSelfAliases) so they never appear as a phantom
third participant, and remoteParticipantIds / the DM-header peer lookup skip
all self aliases.
Adds a DM-header call ring e2e including the cross-signal topology (callee
homed on a secondary signal server) that fails on the old code.

Broadcast a cleared voice_state when voice-active sockets drop and reset mute/deafen flags on disconnect or reconnect so stale session state cannot leak to other clients.
