719262b15d* feat(server): Rework transport architecture and add StreamableHttpTransport - `Server::connect()` no longer contains a processing loop. - `TransportInterface` is updated with `setMessageHandler()` and `listen()`. - `StdioTransport` is updated to implement the new interface. - A new, minimal `StreamableHttpTransport` is added for stateless HTTP. * refactor(server): use event-driven message handling * feat(server): Introduce a formal session management system * fix: ensure session elements are preserved when building server (regression from #46) * refactor: consolidate HTTP example to use shared dependencies * feat(server): Enhance message handling with session support - Updated `TransportInterface` to use `onMessage` for handling incoming messages with session IDs. - Refactored `Server`, `Handler`, and transport classes to accommodate session management using `Uuid`. - Introduced methods for creating sessions with auto-generated and specific UUIDs in `SessionFactory` and `SessionFactoryInterface`. * feat(server): Integrate session management in message handling - Added session support to the `Server` and `Handler` classes, allowing for session data to be managed during message processing. - Updated `TransportInterface` to include session context in the `send` method. - Refactored various request handlers to utilize session information, ensuring proper session handling for incoming requests. - Introduced a file-based session store for persistent session data management * feat: Update session builder method to use set* instead of with* * feat: Fix test compatibility with new session management architecture * chore: apply code style fixes * fix: remove deprecated SSE transport and resolve PHPStan issues
