25	* Remove the entire blog from the Fediverse.
26	*
27	* This command permanently removes your blog from ActivityPub networks by sending
28	* Delete activities to all followers. This action is IRREVERSIBLE.
29	*
30	* ## OPTIONS
31	*
32	* [--status]
33	* : Check the status of the self-destruct process instead of running it.
34	* Use this to monitor progress after initiating the deletion process.
35	*
36	* [--yes]
37	* : Skip the confirmation prompt and proceed with deletion immediately.
38	* Use with extreme caution as this bypasses all safety checks.
39	*
40	* ## EXAMPLES
41	*
42	* # Start the self-destruct process (with confirmation prompt)
43	* $ wp activitypub self-destruct
44	*
45	* # Check the status of an ongoing self-destruct process
46	* $ wp activitypub self-destruct --status
47	*
48	* # Force deletion without confirmation (dangerous!)
49	* $ wp activitypub self-destruct --yes
50	*
51	* ## WHAT THIS DOES
52	*
53	* - Finds all users with ActivityPub capabilities
54	* - Creates Delete activities for each user
55	* - Sends these activities to all followers
56	* - Removes your blog from ActivityPub discovery
57	* - Sets a flag to track completion status
58	*
59	* ## IMPORTANT NOTES
60	*
61	* - This action cannot be undone
62	* - Keep the ActivityPub plugin active during the process
63	* - The process may take several minutes to complete
64	* - You will be notified when the process finishes
65	*
66	* @param array $args The positional arguments (unused).
67	* @param array $assoc_args The associative arguments (--status, --yes).
