Cmux Custom Sidebar

This builds a custom cmux sidebar from a plain language request. Instead of making the user learn SwiftUI syntax or config formats, it takes "show my workspaces and PRs" and writes the interpreted sidebar file directly into ~/.config/cmux/sidebars/, enables the beta flag, selects it, and iterates with hot reload. The sidebars bind to live cmux state (workspaces, tabs, git branches, PRs, clock) and run real cmux commands on tap. It's useful when someone wants their terminal multiplexer UI tailored to their workflow without touching Xcode or build tools. The skill handles the full loop: authoring, validation, selection, and fixing what looks off after the first render.
