Change

Adds /etc/profile.d/caffeinate.sh with:

alias caffeinate='systemd-inhibit --what=idle --who=caffeinate --why="User requested" --mode=block'

(Note: no trailing sleep — takes arbitrary command args)

⚠️ Caffeinate Cluster Overlap

This creates the same file as #360. Exactly one of these two alias PRs should be chosen. The difference: this PR's alias takes any command as args (caffeinate sleep 60), while #360 hardcodes sleep as the wrapped command. This PR's approach is more flexible.

See #360 for the full comparison table.
