feat: uwsm integration and hyprland worktime saver keybinds

- Replace SDDM with greetd+tuigreet (VT1) using uwsm-managed Hyprland
- Remove legacy exec-once from hyprland.conf
- Create 6 systemd user services: hyprpaper, waybar, dunst, hypridle,
  hyprlauncher, cliphist (all WantedBy=graphical-session.target)
- Add worktime saver keybinds: fullscreen, float, cycle windows,
  scratchpad, reload config, browser, keybind menu
- Home row navigation: HJKL for focus, move, resize (SUPER+ALT)
- Replace wofi with hyprlauncher (first-party, uwsm app prefix)
- Add hyprlauncher config with finders: desktop, math, unicode, font
- New ansible role templates: systemd/user services
- Documentation: hyprland-uwsm.md, cheatsheet.txt

+# Hyprland Configuration - uwsm Integration
+
+## Architecture
+
+Session management uses **UWSM** (Universal Wayland Session Manager) wrapping Hyprland in systemd user services.
+
+```
+greetd → tuigreet → uwsm start → systemd user session → Hyprland
+                                    ↓
+              systemd units: hyprpaper, waybar, dunst, hypridle, hyprlauncher, cliphist
+              XDG autostart: Nextcloud, JetBrains Toolbox, Flameshot, etc.
+```
+
+## Session Services
+
+All session services are managed via systemd user units (`~/.config/systemd/user/*.service`):
+
+| Service | Purpose | Status |
+|---------|---------|--------|
+| `hyprpaper.service` | Wallpaper daemon | active |
+| `waybar.service` | Status bar | active |
+| `dunst.service` | Notification daemon | active |
+| `hypridle.service` | Idle/screenlock control | active |
+| `hyprlauncher.service` | App launcher daemon | active |
+| `cliphist.service` | Clipboard history store | active |
+
+### Management Commands
+
+```bash
+# Check all session services
+systemctl --user list-units | grep -E 'hypr|waybar|dunst|cliphist'
+
+# Restart a specific service
+systemctl --user restart waybar.service
+
+# View logs
+journalctl --user -u waybar.service -f
+```
+
+## Launchers
+
+| Component | Tool | Keybind |
+|-----------|------|---------|
+| App Launcher | hyprlauncher | SUPER+D |
+| Keybind Menu | hyprlauncher -o (piped) | SUPER+CTRL+K |
+
+hypr launcher config: `~/.config/hypr/hyprlauncher.conf`
+- `desktop_launch_prefix = uwsm app --` (proper systemd scoping)
+- Cache enabled for frequency-based sorting
+- Finders: desktop (default), math (=), unicode (.), font (')
+
+## Login Manager
+
+**greetd** with **tuigreet** on VT 1.
+Config: `/etc/greetd/config.toml`
+Default command: `tuigreet --time --remember --asterisks --cmd 'uwsm start -e -D Hyprland hyprland.desktop'`
