- ios_voice_unit.rs: add producer_shutdown AtomicBool flag (macOS only).
The macOS start path spawns a tokio producer task that holds clones
of Arc<Mutex<AudioHandler>>, Arc<ArrayQueue<f32>>, and the output
gain/muted atomics, then loops on a 20 ms tokio interval. Without
a shutdown signal the task runs forever on engine stop/restart and
leaks all four Arcs every cycle. Drop now stores 'true' on the
flag; the producer checks it at the top of each tick and exits,
releasing its clones within at most one 20 ms tick.
- macos/Runner/Release.entitlements: strengthen the existing
justification comment for com.apple.security.network.server.
Document the specific failure mode (tokio::net::UdpSocket::bind
-> sandbox 'network-outbound deny' -> EPERM) and explain why
network.client alone does not cover bind()-then-sendto. The
entitlement is required, not over-broad.
