Centralize the per-platform mb_substr truncation that every publisher was repeating into MediaItem::altTextFor(Platform), delete each publisher's private altFor() helper, and clarify the Platform::altTextMaxLength() docblock so it doesn't imply Instagram's documented 1000-char cap is a guess. Add the assertions review flagged as missing: LinkedInPage/ InstagramFacebook alt-text caps, non-string and literal-"0" alt_text normalization, altTextFor() truncation/unsupported-platform behavior, Mastodon's no-description-part case, and the public API's accept/reject path for media.*.meta.alt_text.
