implement-hilla

Implements use cases by creating Hilla views — React/TypeScript views with file-based routing calling @BrowserCallable Java services — and jOOQ queries for the data access layer. Use when the user asks to "implement with Hilla", "create a Hilla view", "build a React view for Vaadin", "create a @BrowserCallable endpoint", or mentions Hilla, client-side Vaadin views, file-based routing, TSX views, or React + jOOQ.
