feat: human-like typing for browser Google and YouTube search

Make the browser search helper search the way a person does: load the
site home page, type the query into the search box one key at a time, and
press Enter — for both Google `search` and `youtube` — instead of jumping
straight to a results URL. Supports the goal of a human-like assistant.
