hermes - 💡(How to fix) Fix [Bug]: Telegram gateway only acknowledges tool requests but never delivers final results

Bug Description Telegram bot (gateway) acknowledges tool-using requests (e.g. "用 x search 搜 post") with "好的，正在搜索……" but then completely fails to execute the tool result delivery back to the user. The session hangs with no final answer.

This is a follow-up / related manifestation of #19287 (Telegram 图片 bug, gateway 只传路径不走 native routing).

Steps to Reproduce

1. Use Hermes via Telegram bot
2. Send message: 用x search，搜索post，关键词gpt image2 提示词
3. Bot immediately replies: "好的，用 x search 搜 post。关键词：gpt image2 提示词 正在搜索……"
4. No further messages, no result, task never completes

Expected Behavior Full tool result (x_search answer with prompt guide) should be delivered back in the same Telegram chat.

Actual Behavior Only intermediate "正在搜索" message, then silence. Tool runs successfully on backend but result is never pushed to TG channel.

Affected Component

• Gateway (Telegram/Discord/Slack/WhatsApp)

Messaging Platform

• Telegram

Debug Report Run hermes debug share on the host and paste links here (user to provide).

Operating System Linux (6.17.0-23-generic)

Hermes Version Current main (as of 2026-05)

Additional Logs / Traceback Gateway appears to handle initial message and tool dispatch, but fails at final answer routing / delivery for non-trivial tool outputs.

Root Cause Analysis (speculative) Likely same root as #19287: gateway routing layer only passes partial data (paths/status) instead of full native result objects back to the Telegram adapter. Tool completion path is broken for TG sessions.

Proposed Fix Ensure gateway fully routes final agent responses (including long tool outputs) via native TG sendMessage after tool execution, similar to how CLI handles final results.
