feat: live charge limit, identity retunes, btop assets (product calls)

- Charge limit: udev GROUP=users on threshold; menu applies sysfs live
  and persists state; boot/AC oneshot prefers live theme-state.json.
- Look & Feel: Reset wallpaper (auto); Theme/next/night light already there.
- NVIDIA first-class wrappers deferred past v1 (keep #59 comments).
- Identity taste: white, lumon, hackerman, matte-black, miasma.
- Hand btop.theme for identity + boreal/executive-slate/neon-glass.

Verified: V0 contrast; V1 battery-charge-limit VM. V3 live sysfs on laptop.

+## 2026-07-10 — Product calls: charge live, identity, btop, NVIDIA skip
+- **Task:** Bernardo decisions on remaining PROPOSED.
+- **Did:** (1) Instant charge-limit: udev GROUP=users on threshold,
+  menu/powermgmt live sysfs + state, oneshot reads live theme-state +
+  AC re-apply. (2) Look & Feel already had Theme/wallpaper/night light;
+  added Reset wallpaper (auto). (3) NVIDIA first-class deferred past v1
+  (HARDWARE.md). (4) Identity retunes: white L-steps, lumon subtext,
+  hackerman surface+UI warn/bad, matte-black subtext, miasma bad.
+  (5) Hand `btop.theme` for 9 identity/whole-swap slugs from palette map.
+- **Verified:** **V0** contrast 24×7; **V1** battery-charge-limit VM
+  (udev restart). **V3** live charge write on real laptop (HARDWARE-QUEUE).
+- **Next suggestion:** only #20/#41 blocked, or Decisions.
