* SurfSense plugin entry point.
*
* Replaces the obsidian-sample-plugin SampleModal/ribbon stub. Lifecycle:
*
* onload():
* load settings seed identity (vault_id, device_id)
* wire api client + queue + sync engine + status bar
* register settings tab register vault + metadataCache events
* register commands (resync, sync current note, open settings)
* register status bar item
* kick off engine.start() (health drain reconcile).
*
* onunload():
* stop the queue's debounce timer; unregistered events and DOM
* handles auto-clean via the Plugin base class.
