🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Add the required byte-wise check for a leading BOM.

The pattern includes \x{feff}, but the workflow still relies only on grep -aPrl. A leading UTF-8 BOM can therefore be removed before pattern matching and pass the gate. Add a separate byte-wise check for EF BB BF at offset zero, then include those files in /tmp/empty-lint-results.txt.

Also applies to: 141-141

In @.github/workflows/dogfood-gate.yml at line 130, Add a separate byte-wise
check in the workflow for files whose first three bytes are the UTF-8 BOM
sequence EF BB BF, independent of the existing grep pattern. Append any matching
files to /tmp/empty-lint-results.txt, alongside results from the PATTERNS and
grep -aPrl checks.

🟡 MEDIUM RISK

Suggestion: To ensure this linter functions as a reliable gate, two improvements are necessary:

  1. PCRE UTF-8 Support: When using grep -P with codepoints like \x{200b}, prefix the pattern with (*UTF8) to ensure the engine treats the input as UTF-8.
  2. Gating Logic: The workflow currently identifies findings but does not exit with a non-zero status. Add logic such as [ "$FINDINGS" -gt 0 ] && exit 1 at the end of the scan step to ensure the CI actually blocks PRs with issues.

🟡 MEDIUM RISK

Suggestion: The -r (recursive) flag is redundant because find is already handling the file traversal. Additionally, switching from \; to + allows find to batch filenames, spawning significantly fewer grep processes and improving CI runtime.
