Feature Request: Support Telegram sendMessageDraft method

Priority: Medium

Description:
Telegram Bot API 9.5 (released March 1, 2026) introduced sendMessageDraft — a method that allows sending a message as a draft, showing a "unsent" preview before the user confirms.

OpenClaw has already implemented this feature (PRs #32180, #32148).

Requesting this feature be added to Hermes Agent to support:

• Sending draft messages that show preview before user confirms
• Integration with existing sendMessage tool patterns

• Telegram Bot API: https://core.telegram.org/bots/api#sendmessagedraft
• OpenClaw implementation: NousResearch/OpenClaw#32180

Use case:
Useful for confirmation workflows where you want users to review a message before it's actually sent.
