fix: add update_browse_history handler and fix verify_apps crash (#156)

Bug 6a: The YouTube task config uses "update_browse_history" to
pre-populate Chrome's history.sqlite with URLs before the agent runs.
This was being skipped as an unknown type. Now translates to a Python
script that kills Chrome, finds the History DB, and INSERTs entries
with proper Chrome timestamps (microseconds since 1601-01-01).

Bug 6b: verify_apps crashed with "AttributeError: 'list' object has
no attribute 'replace'" because the WAA task JSON uses "app" (list)
but the handler expected "apps" (string). Now handles both parameter
names and properly serializes the list with repr().
