On machines with ~1150 processes, each `ps` call takes 30-35s. With 18 sessions enriched in parallel, this caused /api/sessions to take 51+ seconds despite the 2s per-session timeout. Add a module-level TTL cache (5s) with in-flight deduplication so `ps` is called at most once regardless of session count. Also reduce timeouts from 30s to 5s — stale process data isn't useful. Co-Authored-By: Claude Opus 4.6 * fix: guard ps cache callbacks against stale overwrites The .then() and catch callbacks in getCachedProcessList() could clobber a newer in-flight cache entry if the TTL expired and a new request replaced psCache while the old one was still pending.
