Enables Ghostty to render OSC 8 hyperlinks emitted by in-pane processes (Claude Code, statuslines, etc.) as Shift+Cmd+Click-able links. Without these settings, tmux 3.5a + Ghostty 1.3.1 silently drops OSC 8 sequences from in-pane processes, even though raw printf in the same pane renders fine. The fix is three lines: allow-passthrough on, advertise hyperlink capability, and explicit Hls/Hlr terminfo overrides. Verified by: detach + reattach (or kill-server), then printf '\e]8;;https://example.com\e\\link\e]8;;\e\\\n' is clickable with Shift+Cmd+Click. Claude Code's emitted hyperlinks likewise become clickable. Related to tamakiii/meta#773 Co-Authored-By: Claude <noreply@anthropic.com>
