Release 2026.7.7

Revert

• Drop the no-op .catch added to the fetch wrapper in 2026.7.6. It only
  silenced bare fire-and-forget rejections; for the common await / .then
  patterns the rejection propagates to a promise in the page's own code that the
  wrapper cannot reach, so it did not remove the "Failed to fetch" console
  entries and only suppressed fire-and-forget warnings page-wide. The wrapper is
  a transparent passthrough again: a page's own failed fetch is the page's, and
  we only appear in its stack because we wrap fetch.
