Replace <@USERID> tokens with @handles using Slack handle (name) as preferred identifier, falling back to display_name then real_name. Redesign thread rendering with bullet glyphs (● top-level, ◆ thread parent), ├/└ reply branches, horizontal rules between roots, and an ellipsis row for skipped replies. Resolve orphan thread parents from the message cache when possible; otherwise render an explicit "orphaned thread — parent unknown" box.
