Business logic coordination between routes and services.

Controllers should:

• Handle business logic and orchestration between services
• Handle environment variables and configuration
• Coordinate multiple service calls
• Implement business rules and validation
• Handle service business logic layer (result.success)

• Return data objects for routes to handle HTTP responses
• Example: glimpseHandler returns data, route calls c.json(result)

• Handle HTTP requests/responses directly (webhook handler pattern)
• Example: handleUrlWebhook takes Context, returns HTTP responses
• Used for /tasks/* webhook endpoints
