Fixes two read-layer bugs surfaced by a live smoke test of every Apify method:
- fetch_post_engagers was sending
url(string) but the actor now requiresurls(array), so every likers/commenters lookup failed with HTTP 400. Fixed; verified it returns real engagers. - fetch_post_comments was returning the actor's run-summary object as if it were a comment (and returning only that on a zero-comment post). The summary is now filtered out, so callers get clean comment records. Verified: 66 comments on a busy post, 0 on an empty one.
fetch_user_recent_commentsconfirmed healthy.
Combined with v1.0.17 (post-body actor swap), the whole LinkedIn read layer is verified working end to end.
