Fix both fields where an entry has them; the metrics entries carry only a brief description. No event code, metric expression or reported value changes, and the generated tables are not tracked, so the diff is JSON only. ISTALL - the other codespell hit here - is the ETM stall-control bit name, left alone. Written with Hermes Agent, an LLM assistant. Running jevents.py on this change produces none of the three words; perf was not rebuilt, so the perf list output was not checked.
