feat: macOS platform adaptation, concurrency guard and detail page redesign

- web/app.py: IS_DARWIN branches (launchctl kickstart for manual trigger,
  direct execution for digest/continue without sudo); _active_harvests()
  concurrency guard on /run and /continue; normalized detail state
  (last run time from log filename, next trigger computed from schedule)
- detail.html: layout redesign — status badge header, real overview cards,
  merged duplicate run metadata, collapsible logs/config, history moved up
- gitignore: exclude .zcode/
