Summary

• Replace the friends_browser_extension_rest_info filter with a dedicated friends_browser_extension_actions filter on the /wp-json/friends/v1/extension endpoint
• Any plugin can now register actions (with name, url, optional method and fields) shown in the browser extension popup
• Validates that each action has a string name and url, filtering out malformed entries
• Includes PHPDoc with @param/@return and an example for extract-wp-hooks documentation

Test plan

• Verify the /wp-json/friends/v1/extension endpoint returns an actions array when authenticated
• Register a custom action via the filter and confirm it appears in the response
• Confirm malformed actions (missing name/url) are excluded from the response
