This is the live component responsible for the Crashdump pillar: browsing erl_crash.dump files found in the host-allowlisted :crashdump_dirs - pick a dump, watch the parse progress, then read the crash slogan and general counters and dig through the dumped processes (sortable, searchable, with a full per-process drill-down including the stack dump).

Parsing reuses OTP's own :crashdump_viewer (see ObserverWeb.Crashdump); this page is only ever a client of that parser on the dashboard node.
