Add a separate leading-BOM check.

The main grep -aPrl scan does not report a file that begins with EF BB BF, despite PATTERNS containing \x{feff}. Add a prefix check, merge its output into /tmp/empty-lint-results.txt, and deduplicate paths before counting findings.

In @.github/workflows/dogfood-gate.yml at line 118, The PATTERNS scan does not
reliably detect a UTF-8 BOM at the beginning of files. Add a separate
leading-BOM check alongside the existing grep scan, append its matching paths to
/tmp/empty-lint-results.txt, then deduplicate the collected paths before
counting findings.
