Add Cursor-CLI module

[matifali]

Create the cursor-cli module that installs the cursor CLI and uses the agentapi module.

Additionally, add the subdomain parameter to support running cursor-cli under a subdomain with agentapi version >= v0.3.3. This will cause AGENTAPI_CHAT_BASE_PATH to be exported to the correct value and be picked up by the module run script.

See the relevant PR for the goose module for reference (note that it already uses the agentapi module): #299.

• Create cursor-cli module that installs the AgentAPI.
• Ensure task reporting works properly in Coder + Tasks UI
• Option to configure the agent in non-interactive mode.
• 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
