Three improvements stacked into one commit since they share files:
#3 Empty-stage hint: StageGrid no longer disappears when nobody is on
stage. The "Stage" label stays and a quiet "Waiting for speakers…"
line keeps the strip visible so the room doesn't look broken before
the first speaker arrives.
#5 Local per-speaker hush: AudioPlayer gains a setVolume(Float)
default-no-op method; AudioTrackPlayer composes mute and volume
multiplicatively into AudioTrack.setVolume so a hushed stream stays
silent regardless of mute state. NestViewModel exposes
locallyHushed: ImmutableSet<String> in NestUiState plus
setLocalHushed(pubkey, hushed) — applied at attach time so a
re-subscribe of an already-hushed speaker stays silent. New "Hush
this speaker" / "Restore this speaker" row in
ParticipantHostActionsSheet, available to anyone (it affects only
our own playback, nothing on the wire).
#4 Host moderation gaps: wires Promote-to-Moderator using the existing
RoomParticipantActions.setRole(ROLE.MODERATOR) builder — UI gap
only, no protocol change. Adds a new AdminCommandEvent.Action.MUTE
variant + AdminCommandEvent.forceMute(room, target) builder; the
sheet emits it on "Force-mute speaker" and the
AdminCommandsCollector dispatches incoming MUTE actions to a new
NestViewModel.onForceMuted() that routes through the existing
setMicMuted(true) path. Honor-based, same trust model as KICK —
relays don't enforce signer authority, the client checks the
signer is host or moderator on the active kind-30312.
