Write an Kapacitor OOM investigation runbook

Write a runbook for diagnosing (or gathering diagnostic input) Kapacitor OOMs. What are common reasons K might run out of memory - and how to check for them.

Start from the issue body and the Kapacitor repository context, then identify common causes of Kapacitor out-of-memory conditions and the diagnostic information maintainers need. Done means a runbook explains how to investigate or collect input for each relevant cause, with actionable checks.
