Add a separate byte-wise leading-BOM check.

The (*UTF) pattern in .github/workflows/dogfood-gate.yml depends on UTF decoding. A file beginning with EF BB BF and containing malformed UTF-8 can therefore produce a PCRE error and be omitted from the results. Add an LC_ALL=C grep -aPl '^\xEF\xBB\xBF' scan and merge its file list with the Unicode scan.

In @.github/workflows/dogfood-gate.yml at line 130, Add a separate byte-wise
scan using LC_ALL=C grep -aPl with a leading EF BB BF pattern, then merge its
file list with the existing Unicode PATTERNS scan results so BOM-prefixed files
with malformed UTF-8 are included.

⚪ LOW RISK

Suggestion: The -r flag is redundant as find -type f already handles the recursion. Additionally, the script captures the exit status in EL_EXIT but does not act on it. If the scanning process fails due to a syntax error or system issue rather than just finding no matches, the CI will silently pass. Consider validating EL_EXIT to ensure the gate fails if an actual error occurs during the scan.

EL_EXIT=$?
