Teach the launcher what an operating system knows

The OS-parity batch from the vicinae plan, tasks 1 through 7. The audit
came back better than the plan guessed: the calculator already links
libqalculate, the built-in file index answers in under 100ms across all
of home, quicklinks and snippets ship as built-in stores -- so zero new
packages, and `vicinae dmenu` replaces the planned compiled extension
outright. What was missing gets built: a power menu (lock, suspend, log
out through uwsm, restart, power off), reminders as transient systemd
timers with a pick-to-cancel list, a color picker over hyprpicker, and
dmenu pick-lists for window switching, force quit, kill process, SSH
hosts, and recent files -- all through one panama-pick helper. The
launcher commands contract exercises the reminder parsing and every
pick-list against stubs, including killing its own sacrificial sleep.
