Modify the Aider module to add support for Coder Tasks + AgentAPI as a web chat interface.

• Modify coder/agentAPI if needed to Aider (I think it already does)
• Modify Aider Module to install AgentAPI and use it with Aider
• Ensure task reporting works properly in Coder + Tasks UI
• Add a demo to show how it works with the tasks template
• Record a short video showing it working with Coder Tasks and doing status reporting
• Address the points in Improve docs/UX for using AI modules with Tasks #259
