#  migrate-host-binds.sh — repoint dead host keymap targets at Omarchy
#
#  For setups like "Moonrice" whose Hyprland Lua keymap dispatches to a
#  removed shell (global("moonshell:*") IPC calls), this rewrites those
#  entries to live de-omarchy equivalents. Idempotent: skips when nothing
#  matches. Always backs up the file next to itself first.
#
#  Also comments out dead autostart lines in hyprland/execs.lua:
#    wallpaper daemon, moonshell/waybar fallback, hypridle
