docs: rename feder-cr/firefox-stealth refs to feder-cr/invisible-firefox

The companion C++ patches repo at feder-cr/firefox-stealth was deleted
2026-05-19 and the source-of-truth fork was renamed from feder-cr/firefox
to feder-cr/invisible-firefox.  The branch stealth/150 on the renamed
fork is now the single source of truth for all C++ patches.

GitHub's auto-redirect is in effect for the old URLs but is not a
forever guarantee, so update all references now.

Updated:
  README.md         × 2 hyperlinks  (intro paragraph + license section)
  CONTRIBUTING.md   × 3 references  (quick links, scope, bug reports)
  SECURITY.md       × 1 reference   (out-of-scope vulnerabilities)
