Research direction

Start by reviewing the Scala Metals MCP server implementation linked in the issue, especially MetalsMcpServer.scala around line 105, and compare it with the Rust SDK pull request. Determine whether chimp should provide an SSE heartbeat example or a reusable abstraction; done means a documented, usable approach for maintaining MCP server connections.

Written by the indexing model from the issue text.

Description

It's easy to lost connection between MCP server and agent. This issue is faced by many people who create MCP server.
One way to keep connection on server side is implemented heartbeat. Examples of how this was approached in different projects:

Scala Metals
https://github.com/scalameta/metals/blob/39146132ddf16e827e3792c38eef0435b2a5e2f3/metals/src/main/scala/scala/meta/internal/metals/mcp/MetalsMcpServer.scala#L105

Rust SDK
https://github.com/modelcontextprotocol/rust-sdk/pull/74

I think it would be useful for people implementing MCP server to have some example how to do it with chimp (or even better to have some convenient abstraction).
