feat(nvim): add LaTeX workflow; tweak Hyprland master; refresh CS autoexec; add GTK bookmark

Neovim (LaTeX):
- Add TeX ftplugin: spell (en_US,de_DE), soft-wrap + linebreak, conceal=2, no hard wrap
- Add plugins: vimtex (zathura; latexmk with LuaLaTeX + shell-escape),
  LTeX language server via astrolsp + ltex_extra (check on save; motherTongue=de-DE),
  blink.cmp integration (cmp-vimtex, cmp-latex-symbols → insert macros),
  LuaSnip LaTeX snippets, Treesitter “latex”, nabla.nvim (inline/popup math; <leader>mp/<leader>mv)

Hyprland:
- Set master.orientation=left; comment out center_master_* options

Counter-Strike autoexec:
- Rebind +lookatweapon → MOUSE5; map R → lastinv; radio on Y/U/I/H; J → +radialradio
- Crosshair tweaks: size 2.5, gap -3, no outline, alpha off
- Mouse: sensitivity 0.619; zoom_sensitivity_ratio 1.0
- Viewmodel: offset_x -2; cl_prefer_lefthanded 0
- Video/perf: gamma 1.6; set fps_max/fps_max_ui 0; drop legacy perf/network cvars (mat_queue_mode, cl_forcepreload, rate/interp*)
- HUD cleanup: disable target ID; remove +cl_show_team_equipment

GTK:
- Add bookmark: Documents/ttrpg/dsa5
