/**
 * `disk_pressure_status_changed` SSE event.
 *
 * Global broadcast pushed when the daemon's disk-pressure snapshot
 * changes. Mirrors the REST `GET /disk-pressure` status shape so the
 * client's monitor can apply stream updates and polled fetches through
 * the same code path. Carries no `conversationId` — it is workspace-wide.
 *
 * Canonical wire-contract source. Daemon code imports the type
 * directly from this file; external consumers import via
 * `@vellumai/assistant-api`.
