Use `HealthCheck` from `getStatus` tool

What feature do you want to see added?

The part about “health” in

mcp-server-plugin/src/main/java/io/jenkins/plugins/mcp/server/extensions/DefaultMcpServer.java

Line 253 in 45a1bc9

"Checks the health and readiness status of a Jenkins instance, including whether it's in quiet"

is not really true; if you are contacting this plugin at all, clearly the server is at least responding to HTTP traffic and routing Stapler, and mostly the response just reports various things that might be of interest to an admin but are not really timely status.

Suggesting querying the HealthCheck API specifically, and integrating those responses.

https://plugins.jenkins.io/metrics/ is probably too detailed and verbose. It would be useful to know about thread-deadlock but probably that is something to be implemented generically as a HealthCheck where it could be used for example by Kubernetes liveness probes.
