feat(hyprland): add plugins and simplify layouts

Plugins installed via hyprpm:
- hy3: i3-style manual tiling with tab groups (monocle)
- hyprscrolling: PaperWM-style horizontal scrolling
- xtra-dispatchers: throwunfocused, bringallfrom, closeunfocused

Layout system simplified to 4 modes:
- Master (tile) - default DWM-style
- Tab group (monocle) - via hy3 plugin
- Scrolling - horizontal columns
- Floating

New scripts:
- layout-navigate: layout-aware j/k navigation
- Updated cycle-layout: cycles through 4 layouts
- Updated waybar-layout: icons for new layouts

Other changes:
- Add hyprpm reload to startup
- Add cpio and fc-cache to archsetup
- Remove SSH fuzzel picker (conflicted with scrolling keybind)
- Add slidevert animation for scratchpads
- Update todo.org with plugin evaluation notes
