Create a request handler that converts Mist requests to Dream requests

This function creates the main request handler used by the Mist server. It handles the complete request/response cycle:

Convert Mist request headers/metadata to Dream request
Match route to determine if body should be buffered or streamed
Read body (buffered) or wrap stream (streaming)
Route the request through the router
Convert Dream response back to Mist format
Handle HTTP → WebSocket upgrades when a controller calls websocket.upgrade_websocket (the upgrade response is stashed and returned here instead of a normal HTTP response)

Parameters

router: The application’s router with all routes configured
max_body_size: Maximum allowed request body size in bytes
template_context: Template context to clone for each request
services_instance: Application services (database, cache, etc.)
update_context: Function to update context with request-specific data

Returns

A function that takes a Mist HTTP request and returns a Mist HTTP response. This function is what you pass to mist.new().
