LinkedIn API Authentication:

• Create LinkedIn app at https://www.linkedin.com/developers/apps
• Add credentials to .env:

LINKEDIN_CLIENT_ID=your_client_id
   LINKEDIN_CLIENT_SECRET=your_secret
   LINKEDIN_ACCESS_TOKEN=your_token (auto-generated on first use)

Without API setup: Command still generates the post content for manual copy-paste. Note: Works in ANY repo type (Python, Rust, Go, etc.) - uses only bash and curl, no Node.js required.
