feat(keybinds): live keybind reminder overlay

Modelled on window-switcher: a Scope with a 1x1 keepalive PanelWindow
plus a LazyLoader'd overlay, opened via IpcHandler (SUPER+k is bound
in a different repo). hyprctl binds -j is asked fresh on every opening
so the list matches whatever Hyprland has loaded, with Binds.group()
from task 1 turning it into the grid's {name, rows} groups.

+# keybinds
+
+Every Hyprland keybind with what it does, grouped, over a dimmed screen.
+SUPER+k opens it, Escape or a click closes it.
+
+The list is `hyprctl binds -j`, asked on every opening, so it is what Hyprland
+has loaded: binds generated in Lua loops included, and an edit to
+`keybindings.lua` shows once `hyprctl reload` makes it real, not before.
+There is no cache to go stale.
+
+`hyprctl` reports every Lua action as `__lua` with an opaque number, so the
+text comes from each bind's `description` option, written `Group: Label`:
+
+    hl.bind("SUPER + w", hl.dsp.exec_cmd(P.browser), { description = "Apps: Browser" })
+
+The part before `: ` is the heading. A bind with no description is listed
+last under "Undescribed", so a missing one shows instead of vanishing.
+
+## Running
+
+    qs -p ./keybinds
+    qs -p ./keybinds ipc call keybinds toggle
+
+## Blur
+
+Optional, in the Hyprland config:
+
+    hl.layer_rule({
+        name         = "blur-keybinds",
+        match        = { namespace = "^(quickshell-keybinds)$" },
+        blur         = true,
+        xray         = false,
+        ignore_alpha = 0.1,
+    })
+
+## Check
+
+    node keybinds/test_binds.js
