fix(chatwoot): destroy() now removes the widget DOM + clears storage

Chatwoot's SDK leaves its iframe and bubble holder in the DOM even after
\$chatwoot.reset(). destroy() now explicitly removes:
- #cw-widget-holder, #cw-bubble-holder, .woot-widget-holder,
  .woot-widget-bubble, .woot--bubble-holder, iframe.woot-widget-holder
- localStorage keys containing 'chatwoot' (try/catch so blocked storage
  doesn't throw)

Fixes the 'destroy basmadim kaybolmadi' report — after destroy() the
widget is fully gone and load() starts fresh.

env.d.ts gains a minimal Storage interface for the localStorage usage.
