Gap surfaced by OmniCopilot#16: the Chaos Mode dashboard page, its per-key
chaosModeEnabled permission and both dispatch endpoints had no setup doc at
all (only the auto/chaos table line existed), and AUTO-COMBO.md never stated
that weighted is a proportional draw where zero-weight steps are never drawn.
New docs/guides/CHAOS-MODE.md (registered in meta.json + docs/README.md) and
a 'weighted semantics' subsection under the strategy table, both written from
the code (chaosConfig.ts, chaosExecutor.ts, both routes, targetSorters.ts,
targetResolution.ts). check:docs-all exits 0.
