Feature request: Telegram Forum Topics support

Summary

It would be useful if the official Telegram integration supported Forum Topics so different topics in the same Telegram group could map to separate Claude Code conversations.

Use Case

Telegram Forum Topics are a natural way to separate conversations by purpose, such as coding, research, and general discussion. Without topic-aware routing, messages from different subjects can end up sharing the same conversation context.

Suggested Approach

Telegram's Bot API includes a message_thread_id for forum-topic messages. Supporting this field in the official integration would make it possible to keep replies attached to the correct topic and preserve cleaner context boundaries between conversations.

Example:

• Topic "Coding" → conversation A
• Topic "Research" → conversation B
• Topic "General" → conversation C

Why This Would Help

• Reduces context pollution between unrelated discussions
• Makes Telegram forums behave more like channel-based workspaces
• Improves long-running workflows that benefit from topic-level separation

Happy to provide more details about the Telegram Forum Topics UX if that would be useful.
