Fix the grep pattern before relying on invisible-character detection.

GNU grep 3.8 rejects code-point escapes above \x{ff} and exits with status 2 before scanning files. Replace these escapes with UTF-8 byte sequences, including EF BB BF for BOM detection.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In @.github/workflows/dogfood-gate.yml at line 113, Update the PATTERNS
definition in the dogfood gate workflow to replace unsupported \x{...} escapes
above \x{ff} with their UTF-8 byte sequences, including EF BB BF for BOM
detection, while preserving detection of the existing invisible characters.

⚪ LOW RISK

Suggestion: The -r flag is redundant when using find to provide specific file paths to grep. Using -exec ... {} + instead of -exec ... {} \; is significantly more efficient for large repositories as it reduces the number of process forks. Additionally, removing 2>/dev/null is recommended so that any PCRE compilation or environment errors are visible in the CI logs.
