 * FleetEvent, discriminated union of live process-registry lifecycle events.
 *
 * These are the wire-surfaced, poll-free counterpart to the ProcessRegistry's
 * in-process coalesced snapshot tick: an emit-bridge diffs consecutive registry
 * snapshots and emits these per-node lifecycle deltas onto the runtime event bus
 * `fleet` domain, which the control-plane gateway already fans out to subscribed
 * SSE/WebSocket clients (no new channel). Every field here is DERIVED from the
 * authoritative snapshot, the events carry no state the snapshot does not, in
 * keeping with the registry's contract ("a view, not a second source of truth").
 *
 * The kind/state/attention string unions are structural duplicates of
 * ProcessKind / ProcessState / ProcessAttentionReason
 * (platform/runtime/fleet/types.ts), kept inline so this leaf event module stays
 * free of a `platform/` import, the same independence precedent as AgentUsage
 * in ./agents.ts.
