1// Package telegram implements zot's Telegram bot bridge.
2//
3// It runs in-process, polling Telegram for DMs and forwarding them to
4// a core.Agent. Responses stream back as Telegram messages. Images
5// sent by the user are downloaded and attached to the next prompt as
6// provider.ImageBlock, so vision-capable models see them the same way
7// they would via drag-and-drop in the TUI.
8//
9// State (bot token, allowed user id) lives in $ZOT_HOME/bot.json.
