refactor(hypr): namespace config under sjb/

Move the Hyprland Lua modules into config/hypr/sjb/ with init.lua as the
entry point, so the whole config tree can be symlinked per-file and the
unmanaged hypr*.conf files keep their own symlinks. Add an sjb block that
requires the new entry point.

While here: bind the second Lenovo L15, force 3440x1440@144 on the
MAG342CQR, use the named 2fg scroll method, and drop dead locals.

Switch the skills mise task to clone/pull SjB/skills into
~/.local/share/skills and symlink it, replacing the npx skills adds.

config/hypr/sjb/envs.lua
