Prepend [msg:chatId:messageId] [YYYY-MM-DD HH:MM] to messages sent to the LLM, giving the model awareness of message timing and identifiers. Changes: - router.ts: add date field (Unix epoch) to TelegramInboundEnvelope - worker-runtime.ts: formatMessagePrefix helper + prefixPrompt wrapper that skips slash commands (preserves ^/ anchored parsing in rpc.ts) - Prefix applied at 5 RPC call sites (image, audio, text foreground + 2 background fork points) - Timezone configurable via TELEGRAM_TIMESTAMP_TZ env var (default UTC) - Backwards compatible: missing date field on queued items produces prefix without timestamp bracket
