Subject: [PATCH] Fix CI failures blocking 1.3.2 release
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Rubocop Style/RedundantRegexpEscape: remove unnecessary \- in two
  character classes in FULL_EMAIL_REGEXP (user.rb:59)
- Brakeman LinkToHref XSS: add fingerprint to brakeman.ignore — the
  filter_path guard (start_with?('/')) prevents javascript: and
  absolute-URL attacks; Brakeman still tracks params[:path] taint
  through the conditional assignment
- RSpec install: switch pdfium binary source from the deleted
  docusealco/pdfium-binaries to bblanchon/pdfium-binaries (same
  tarball layout: lib/libpdfium.so)
