Rebase this fork's tab-bar and compact-bar plugins onto a newer zellij upstream release. Use when the user asks to "rebase on upstream", "update to zellij vX.Y.Z", "bump zellij version", "pull in latest zellij", or any equivalent. The fork extracts default-plugins from zellij-org/zellij and adds two orthogonal customizations (show_tab_indices + permissions handshake); this skill walks through snapshot-and-reapply, verification, tagging, and release.
