Address 7 memory/architecture issues affecting long-running gateway processes on embedded devices (<10MB RAM): - Fix dispatcher busy-wait: remove select+default pattern that caused CPU spin after context cancellation; SubscribeOutbound handles ctx internally - Add TTL janitor for typingStops/placeholders sync.Map entries to prevent unbounded accumulation when outbound paths fail - Reduce queue buffers from 100 to 16 slots (~84% memory reduction) - Optimize SplitMessage with index-based rune operations to reduce intermediate string/rune allocations - Replace uuid.New() with atomic counter + random prefix for media scope IDs (eliminates per-call crypto/rand syscall) - Lazy channel worker creation: defer goroutine+buffer allocation until channel.Start() succeeds
