Pull Request Overview

Adds the ability to filter which screen options appear on the ActivityPub settings page and refactors the existing static checkbox logic into a loop over a filterable array.

• Introduces a activitypub_screen_options filter for customizing available screen options.
• Replaces hard-coded POST handling with a loop that saves any filtered options.
• Converts the HTML output to a buffer and generates inputs dynamically.

• The docblock for the activitypub_screen_options filter is missing a @return annotation. Please add @return string[] to describe the expected format of the filtered array.

$screen_options = \apply_filters( 'activitypub_screen_options', $screen_options );

• [nitpick] There are no tests covering the new filterable screen options. Consider adding unit or integration tests that hook into activitypub_screen_options to verify custom options are rendered and saved correctly.

foreach ( $screen_options as $option => $label ) {
