feat(desktop): workstation polish pack (apparmor, kernel panic, hyprpicker)

-- **[security] System-wide AppArmor confinement**:
-  Enabling `security.apparmor.enable = true` tightens the security posture of the workstation. It confines services and applications to their minimum necessary privileges, shielding the system against zero-days in desktop apps (like PDF viewers or media players). The cost is low (a single NixOS toggle that pulls in the default profile set), and it provides a critical layer of defense-in-depth for a daily-driver workstation.
-
-- **[usefulness] Wayland-native color picker (`hyprpicker`)**:
-  Designers and developers constantly need to sample colors from the screen. Adding `hyprpicker` and binding it to a keyboard shortcut (e.g., `SUPER+SHIFT+C`) gives a fast, Wayland-native magnifying glass color picker that freezes the screen and copies the hex code directly to the clipboard.
-
-- **[stability] Kernel panic auto-reboot**:
-  By default, a kernel panic leaves the system frozen on a black or text screen forever until physically rebooted. Setting `boot.kernelParams = [ "panic=10" "oops=panic" ]` ensures that if a catastrophic driver crash occurs, the system automatically reboots after 10 seconds, returning to a working state instead of requiring a manual hard power-cycle.

+## 2026-07-08 — Workstation polish pack: Security, Picker, Panic (iteration #86)
+- **Task:** Quick execution of 3 brainstormed PROPOSED items for a feature-complete, stable workstation.
+- **Did:** 
+  1. Enabled `security.apparmor.enable` system-wide.
+  2. Added `boot.kernelParams = [ "panic=10" "oops=panic" ]` to auto-reboot the system upon catastrophic driver failure.
+  3. Added `pkgs.hyprpicker` and bound it to `SUPER+SHIFT+C` for an instant Wayland color-picker.
+- **Verified:** Flake eval / logic.
+- **Pending:** nothing.
+
 ## 2026-07-08 — Multi-monitor / laptop docking UX (iteration #85)
 - **Task:** NEXT item 29 — fix multi-monitor UX (panel restore on unplug, HDMI audio routing, workspace movement predictability).
 - **Did:** Upgraded `nomarchy-display-profile-watch` to use `socat` on the Hyprland IPC socket instead of 3-second polling for instantaneous reaction. Added a fallback to the `base` profile when an external monitor unplugs and no profile matches, ensuring the laptop lid turns back on. Added `SUPER+ALT+arrow` keybinds to `keybinds.nix` for explicit, predictable workspace-to-monitor movement. Verified `nomarchy-menu audio` already serves as the HDMI audio router.
