- bin/setup.sh: one-command machine bootstrap (auto platform detect) —
  directory layout, dependency check (brew install on consent), claude
  auth check, skills repo auto-clone from SKILLS_REPO_URL + npm install
  + full bundle import (all sources), dual skill symlink registration,
  default.conf/web.conf generation (random panel password), optional
  web panel service install, digest schedule, remaining-manual-steps
  summary; idempotent
- web/app.py: platform_layer integration — paths/timer reads/trigger/
  active-harvest checks unified; add/edit/disable actions now work on
  darwin; per-source harvest toggle route (schedule load/unload +
  skill enable/disable; auto staggered schedule creation on first enable)
- index.html: toggle switch column, unscheduled skill sources merged
  into list, platform-neutral labels
- bin/platform_layer.py: python facade reusing platform.sh via
  'platform.sh call' dispatcher for all mutations; file reads native
