Updates

User actions arrive as Updates over webhook or getUpdates.

Common types

message / edited_message / message_deleted
message_read / message_delivered (opt-in via allowed_updates; included in setWebhook defaults)
callback_query, inline_query
friend_request, my_chat_member, chat_member, chat_join_request

Inbound message updates use a deterministic update_id. Webhook sends X-StarIM-Update-Id. Still dedupe on the client for retries.
