Adds Delay Before Emitting PLUGIN_CREATED and PLUGIN_UPDATED Events

Last updated: 7 Feb 2025

When a plugin is created or updated, we emit the PLUGIN_CREATED and PLUGIN_UPDATED events. These events were firing immediately, which means the plugin likely wasn’t installed at the time the event was emitted. This change introduces a delay before emitting these specific events, which should make this problem appear less frequently. A more durable fix will be implemented in the future.
