Adds <summary>/<param>/<returns>/<inheritdoc> where missing and removes project bookkeeping IDs (task/tracking refs) from shipped code comments, so the docs read cleanly and CommentChecker is quiet except for known false positives (PLC/protocol terms, event/IEqualityComparer inheritdoc). Doc/comment-only; no logic changed; solution builds clean.
