feat(settings): relocate Gesture Control into Input section + release 0.8.2

- Move the Gesture Control (beta) toggle into the existing Input section
  (alongside Local Echo / CJK Input / Extended Keyboard Bar); remove the
  duplicate "Input" section header. Hide only the toggle (not the whole
  section) when CODEMAN_GESTURE=1 is unset.
- scripts/codeman-web.service: set CODEMAN_GESTURE=1 so the gesture feature
  is available on the local install (still gated by the default-OFF toggle).
- CLAUDE.md: version sync to 0.8.2 + config/app.js structural-count fixes.
- Version packages -> 0.8.2 (changeset covers detach, gesture overlay,
  multi-monitor, settings toggles, cache-busting).
