Go page (/workspace/{id}/go): parse three [data-slot=usage-item] frames
(Rolling/Weekly/Monthly) into usage percentages + computed resets_at from the
relative reset-duration text. Zen page (/workspace/{id}): parse
[data-slot=balance] b into remaining + currency unit. Add an offline unit test
against tmp/ captures. Fix pretty renderer (percent display, money format,
day-aware relative times). Update DESIGN.md, README, examples and config
template to the real wrk_ workspace ids.
