Show Herdr keybindings with SUPER + CTRL + K
Mirrors the Tmux keybindings menu on SUPER + ALT + K. Herdr has no CLI that dumps resolved bindings, so the action list and its defaults come from `herdr --default-config`, where every action appears as a commented assignment, and the user config overrides what it sets. Prose in that default config can read like an assignment, as in `# type = "popup" opens a session-modal terminal`, so a line counts only when its value is a bare string or an array of them. Both TOML quote characters open a string, and with no config file at all the listing shows Herdr's own defaults rather than the Omarchy seed config Herdr never loaded.
