MelekiandClaude Opus 4.8 e395927a67 Send cronjob result and notify-agent reaction to Telegram
The cronjob notification ran the notify-agent on the result summary and
sent only its reaction to Telegram. When the agent merely acknowledged the
summary (e.g. "👍"), the actual cronjob result never reached Telegram —
the user got a header plus an emoji and no information.

Send the real result as the guaranteed first Telegram message, then run
the notify-agent best-effort and send its reaction as a separate second
message. The agent run is wrapped in try/catch with a canRunNotifyAgent
guard instead of the old return-aborts, so a missing key / OpenAI without
key / unavailable CLI only skips the reaction — the result is already
delivered. The notify-agent still persists its reaction to the web history
automatically (ChatNonStreaming / ChatNonStreamingViaCli).

TelegramService.SendNotification now uses SendLongMessage so long results
are chunked into 4096-char messages instead of being rejected whole.
