# telegram-bootstrap.sh — Universal SIN Telegram Bot Bootstrap
# Usage: ./scripts/telegram-bootstrap.sh [--bot-name <alias>] [--env-file <path>]
# Reads TELEGRAM_BOT_TOKEN (+ optional TELEGRAM_BOT_NAME) from .env,
# registers the bot with sin-telegrambot CLI, and bootstraps the chat_id.
# Zero manual steps required.
#
# Prerequisites:
#   - sin-telegrambot CLI installed: ~/.local/bin/sin-telegrambot
#   - Telegram.app installed on macOS (for auto-bootstrap via AppleScript)
#   - .env file in project root with TELEGRAM_BOT_TOKEN set
#
# Part of: A2A-SIN-Agent-Template canonical scripts
# Canonical CLI: sin-telegrambot (https://github.com/Delqhi/sin-telegrambot-cli)
