Quick Copy: “Copy” button directly in the post/term listing in the admin panel.

Developer Notes
Namespace: Melk\\UrlShortenerByMelk.
Unique prefix: all functions, options, meta keys and hooks use the urlshbym_ prefix, following the WordPress Plugin Handbook recommendations to avoid naming collisions.
Options stored in the database:
urlshbym_enabled_post_types
urlshbym_enabled_taxonomies
Meta keys:
_urlshbym_short_code on posts
_urlshbym_short_code on terms (taxonomies)
Database table: {$wpdb->prefix}urlshbym_short_urls is created on activation to store the mapping between short codes and objects.
Main hook:
urlshbym_short_url_clicked — fired whenever a short URL is accessed, receiving the short code and the internal record ID.
Integration helper: urlshbym_get_short_url_for_post( $post_id ) — a global function other plugins (such as Social Kit by Melk) can call via function_exists() to reuse the short URL, with no hard dependency in either direction.
Resolution: on template_redirect (priority 1), only when the main query is a 404, a root-level path of 5-7 alphanumeric characters is looked up in the table and redirected with a 301. No rewrite rules are registered.
Options also stored: urlshbym_delete_data_on_uninstall, urlshbym_db_version.
