v13: Plugin-managed editor/sidebar orchestration, deterministic sidebar controls, and cleaner Zellij workspace navigation

[luccahuguet]

• The Biggest Pain Points Are Fixed – v13 replaces fragile pane-scanning flows with a real Zellij plugin (written in rust!) that tracks the managed editor and sidebar panes and routes workspace actions directly instead of relying on shell heuristics
• The Sidebar Can Always Find the Editor – The sidebar can now always find the managed editor pane and open files in it reliably, and it is much faster because Yazelix no longer has to walk through panes or rely on pane-scanning heuristics
• Sidebar and Layout Controls Are Finally Separate – Sidebar open/close now has its own Ctrl+y binding instead of being entangled with layout-family switching on Alt+[ and Alt+]
• Deterministic Workspace Navigation – Alt+y toggles focus between the managed editor and sidebar, while Alt+[ and Alt+] switch predictably between the single, vertical split, and bottom terminal layouts
• Better Config Inspection – yzx config now supports focused section views for hx, yazi, and zellij, plus yzx config open
• Simpler Update and Testing Commands – yzx update and yzx dev test were simplified into clearer defaults that are easier to remember and safer to use
• Clearer Refresh and Environment Feedback – yzx env now shows rebuild activity more clearly, launch paths skip noisy shell-hook welcomes, and Yazelix warns when runtime versions drift
• Command Palette – yzx menu gives you a searchable command palette for the main Yazelix actions, including a popup mode inside Zellij on Alt+Shift+m
• Refresh Workflow – yzx refresh makes it easier to rebuild the Yazelix environment without launching the UI, while yzx restart cleanly switches the current window onto the refreshed profile (as before)
