v1.0.52: add Launch Nextcloud button

Spawns the Nextcloud.app binary directly (detached, no Terminal window)
since it doesn't register properly with launch services on some setups.
New action requires a one-time plugin reinstall (manifest changes don't
ship through the OTA updater, which only touches plugin.js + assets).
