The proxy configuration (`channels.telegram.proxy`) was only used for
the gateway monitor (polling), but not for outbound sends (sendMessage,
reactMessage, deleteMessage). This caused outbound messages to bypass
the configured proxy, which is problematic for users behind corporate
proxies or those who want to route all traffic through a specific proxy.
This change ensures that all three outbound functions use the same
proxy configuration as the monitor:
- sendMessageTelegram
- reactMessageTelegram
- deleteMessageTelegram

Add channels.telegram.linkPreview config to control whether link previews
are shown in outbound messages. When set to false, uses Telegram's
link_preview_options.is_disabled to suppress URL previews.
- Add linkPreview to TelegramAccountConfig type
- Add Zod schema validation for linkPreview
- Pass link_preview_options to sendMessage in send.ts and bot/delivery.ts
- Propagate linkPreview config through deliverReplies callers
- Add tests for link preview behavior

Telegram General topic (id=1) has inconsistent API behavior:
- sendMessage: rejects explicit message_thread_id=1
- sendChatAction: requires message_thread_id=1 for typing to show
Split into two helper functions:
- buildTelegramThreadParams: excludes General topic for messages
- buildTypingThreadParams: includes General topic for typing
Add ability to delete messages in Telegram chats via the message tool.
Changes:
- Add deleteMessageTelegram function in send.ts
- Add deleteMessage action handler in telegram-actions.ts
- Add delete action support in telegram message plugin adapter
- Add deleteMessage to TelegramActionConfig type
- Update message tool description to mention delete action
Usage:
- Via message tool: action="delete", chatId, messageId
- Can be disabled via channels.telegram.actions.deleteMessage=false
Limitations (Telegram API):
- Bot can delete its own messages in any chat
- Bot can delete others' messages only if admin with "Delete Messages"
- Messages older than 48h in groups may fail to delete
Use Telegram's sendVoice API for audio files by default, displaying them
as round playable voice bubbles instead of file attachments.
Changes:
- Add asVoice option to TelegramSendOpts (defaults to true)
- When asVoice is true (default): use api.sendVoice() for voice bubbles
- When asVoice is false: use api.sendAudio() for traditional audio files
This gives callers control: voice messages for TTS/quick responses,
audio files for music/podcasts with metadata display.
