A production-grade, zero-config Telegram bot that cross-posts content to 
Twitter (X), Mastodon, LinkedIn, and Facebook. 

This tool runs as a standalone CLI using only the Python standard library 
and the 'requests' library. It handles asynchronous scheduling, image 
processing, and platform-specific API nuances (including OAuth 1.0a signing 
for Twitter and the complex multi-step image upload flow for LinkedIn).

Usage:
    1. Install dependencies: pip install requests
    2. Set Environment Variables:
       export TELEGRAM_BOT_TOKEN="..."
       export TWITTER_API_KEY="..." 
       export TWITTER_API_SECRET="..."
       export TWITTER_ACCESS_TOKEN="..."
       export TWITTER_ACCESS_SECRET="..."
       export MASTODON_TOKEN="..." 
       export MASTODON_INSTANCE="https://mastodon.social"
       export LINKEDIN_TOKEN="..."
       export LINKEDIN_URN="..." (e.g., urn:li:person:abc123)
       export LINKEDIN_ORG_URN="..." (Optional, defaults to person)
