Remove noisy agent toasts and debug logging

Remove the "Refreshing" and "Failed to refresh agent" toasts from the
agent panel — they fire frequently but are meaningless since sync
recovers transparently. The "Reconnecting..." toast for host disconnect
is preserved.

Strip debug console.log calls across the app: render tracking in
message/stream views, dependency change tracking in workspace screen,
terminal tab slot logging, and verbose audio engine/voice runtime
bridge stats logging. Legitimate console.error/warn in catch blocks
are kept.
