* plugin-runtime: expose runHeartbeatOnce in system API
Plugins that enqueue system events and need the agent to deliver
responses to the originating channel currently have no way to
override the default `heartbeat.target: "none"` behaviour.
Expose `runHeartbeatOnce` in the plugin runtime `system` namespace
so plugins can trigger a single heartbeat cycle with an explicit
`heartbeat: { target: "last" }` override — the same pattern the
cron service already uses (see #28508).
Changes:
- Add `RunHeartbeatOnceOptions` type and `runHeartbeatOnce` to
`PluginRuntimeCore.system` (types-core.ts)
- Wire the function through a thin wrapper in runtime-system.ts
- Update the test-utils plugin-runtime mock
