Merge origin/master into feat/preset-scoped-schedule-tools

Resolutions:
- `docs/subsystems/schedule.*` and `packages/client/ui-schedule/README.*` keep
  this branch's shipped-composition text with master's newer wording (Rules and
  Records tabs, the icon-button linked-session layout).
- `docs/event-producer-consumer.*` regenerated by `gen-doc-graphs`.
