feat: the cache and slackware cards move to quickshell

Both cards are now drawn by quickshell, so the conky copies go: the two
widgets, their samplers and texeci lines, their fixtures and icons, and
du_parse with human_bytes, which only the cache card used. kv_parse stays
for breaktimer; its test now runs on an inline string. README gains a
Samplers section listing what conky still schedules, and DESIGN.md's
examples point at the cards that remain. Their slots in the layout are
left open.
