Azure SQL Developer: serverless API + event-driven with Azure Functions

Build HTTP CRUD endpoints and change-driven handlers over the local Azure SQL Developer (Private Preview) using Azure Functions and the first-party Azure SQL bindings. Two capabilities:

• API: HTTP-triggered functions with SQL input and output bindings (read and upsert with no ADO.NET boilerplate).
• Event-driven (local): the SQL trigger binding fires a function when rows are inserted/updated/deleted. It is backed by Change Tracking, runs fully locally against the container, and needs no cloud services.

Event-driven note: Azure SQL Change Event Streaming (CES) is the cloud path for streaming row changes, and it cannot run against the local container (it is unsupported on the Linux engine and streams only to Azure Event Hubs public endpoints). Locally, use the SQL trigger below. See references/event-driven.md.
