feat(rofi): battery charge-limit toggle in the System menu

Add a `batterylimit` nomarchy-menu subcommand — a preset picker
(80/90/60/Off/Custom…) that writes settings.power.batteryChargeLimit via
theme-sync (--no-switch; lands on the next sys-rebuild, power.nix's oneshot
applies it). Surfaced as a first-class System row, self-gated on the
charge_control_end_threshold sysfs node like Power profile.

Moved out of the gum control-center (removed its Battery Limit case +
choose entry) so the toggle lives in one place — the rofi menu Bernardo
actually uses, per his request.

+## 2026-07-07 — Battery-limit toggle in rofi System (iteration #64, item 36a)
+- **Task:** BACKLOG item 36(a) — Bernardo wanted the charge-threshold
+  toggle as a first-class row in `nomarchy-menu › System`, not buried in
+  the gum control-center where #55 put it.
+- **Fix:** `rofi.nix` — new `batterylimit` subcommand: a preset picker
+  (80%/90%/60%/Off/Custom…) with battery-0XX icons, writing the baked
+  `settings.power.batteryChargeLimit` via theme-sync `--no-switch` (lands
+  on next sys-rebuild; power.nix's oneshot applies it). Added a System row
+  self-gated on the `charge_control_end_threshold` sysfs node (like Power
+  profile), dispatch, and usage string. **Moved** — removed the duplicate
+  "Battery Limit" case + choose entry from `nomarchy-control-center.sh` so
+  it lives in one place.
+- **Verified:** V0 green. V1: control-center builds clean (shellcheck),
+  home activation builds clean (writeShellScriptBin's `bash -n` on the
+  menu passed); grepped the built script to confirm the row/dispatch/case/
+  guard are all present. Live menu interaction is a V3 check (queued).
