Strip <header> chrome before Readability parses; show full article title in reader content

- Confirmed live (Ars Technica): a section-kicker badge, the dek/subhead, and
  an orphaned duplicate hero-image caption were all leaking into extracted
  content because they live in a <header> Readability doesn't exclude by tag,
  only deprioritizes in scoring. Strip <header> from the DOM ourselves before
  handing off to Readability -- a pre-processing decision on our side, not a
  change to Readability's own algorithm, per instruction not to touch it.
- Render the article's full title as a heading at the top of the reader
  content itself (wrapReaderHtml), not just the top bar, which truncates to
  one line. This also replaces whatever heading Readability happened to keep
  in-body, now that <header> (and any <h1> inside it) is stripped pre-parse.
- Bump extraction timeout 15s -> 25s: confirmed live, several heavy
  real-world pages were timing out before onPageFinished ever fired, well
  short of a real parsing failure.
