feat: disk space monitor with desktop notifications + waybar indicator

Adds a disk monitor script that warns via notify-send (swaync) when disk usage exceeds 85% (warning) or 92% (critical), and shows a color-coded indicator in the waybar. Changes: - waybar/scripts/disk-monitor.sh — monitoring script with 3 modes: * daemon: background check every 5 min, sends desktop notifications * waybar: one-shot JSON for waybar custom module * check: single check for manual use - hyprland.conf — exec-once for daemon mode (runs on login) - config.jsonc — added custom/disk-monitor to modules-right - modules.json — custom module definition (60s refresh, color-coded) - style.css — normal/warning/critical styles with blink animation Usage: Normal: shows 💾 / 45% (green) Warning: 🟡 / 85% (orange) Critical: 🔴 / 92% (red, blinking)

-*** WireGuard Module
-The Waybar includes a custom WireGuard VPN status module that shows connection status, TX/RX stats, and peer info.
-
-Setup:
-
-1. Install openresolv (needed by wg-quick for DNS):
-   #+begin_src bash :tangle no
-   sudo pacman -S openresolv
-   #+end_src
-
-2. Configure sudo for wg-quick (required for click-to-toggle binds):
-   #+begin_src bash :tangle no
-   echo "$USER ALL=(ALL) NOPASSWD: /usr/bin/wg-quick" | sudo tee /etc/sudoers.d/wireguard
-   #+end_src
-
-3. Create a WireGuard config (if not exists):
-   #+begin_src bash :tangle no
-   sudo cp /etc/wireguard/work-laptop.conf /etc/wireguard/
-   sudo chmod 600 /etc/wireguard/work-laptop.conf
-   #+end_src
-
-4. Refresh Waybar to pick up new config:
-   #+begin_src bash :tangle no
-   killall -q waybar && waybar -c ~/.config/waybar/config.jsonc & -s ~/.config/waybar/style.css &
-   #+end_src
-
-Or use the launch script:
-   #+begin_src bash :tangle no
-   ~/.config/waybar/launch.sh
-   #+end_src
-
-Keybinds:
- ~$mainMod+Ctrl+V~ — Connect WireGuard (work-laptop)
- ~$mainMod+Ctrl+Shift+V~ — Disconnect WireGuard
-
-The module polls /usr/bin/wg every 10 seconds. It shows a lock icon with TX/RX when connected, or an unlock icon when disconnected.
