feat(sway): wire XF86 media keys (Display/Tools/Keyboard/Favorites)

- XF86Display replaces F7 for display-toggle.sh (dedicated HW key)
- XF86Tools opens floating pulsemixer (audio mixer TUI)
- XF86Keyboard opens KEYBINDS.md in glow (floating pager)
- XF86Favorites takes over mako history picker (from Super+Alt+n)

Adds generic [app_id="floating"] window rule so ghostty --class=floating
windows open floating. Adds glow to meta/base.txt.
