Like a post — or a comment: pass replyTo (a reply id from list_replies) to like that comment instead of the post. Idempotent: if it is already liked the call succeeds with already: true and nothing is toggled. There is no unlike. Works on Naver Blog and on Instagram accounts connected through Facebook that hold the like permission; any other Instagram account and every other channel answer not_supported. A Facebook-connected Instagram account without that permission answers feature_in_review while the permission is in Meta app review (list_platforms shows the state), and reconsent_required once it can be granted by reconnecting. On Naver Blog the post can belong to another blog: pass its link and we act as the connected account. Naver ignores liking your own post, and that comes back as naver_not_allowed rather than a fake success. On Naver Blog a secret comment, a comment hidden by Cleanbot or by the blog's blocked keywords, and every comment on a blog that turned comment likes off have no like button; those answer naver_not_allowed too, and retrying does not help. If the response carries bridge, bridge.nextStep says what is needed: run_wake means Chrome with the extension is closed, so tell the person bridge.userMessage with the bridge.wake command for their OS and retry once after they say Chrome is open; ask_user_login / ask_user_update mean tell the person bridge.userMessage. Do not retry more than twice.
