Fix YAML syntax error: remove BOM and malformed UTF-8 sequences

[Copilot]

The workflow file contained a UTF-8 BOM and malformed multi-byte UTF-8 sequences (control characters 0x80-0x9F) that caused YAML parsing to fail with "unacceptable character" errors.

Changes

• Removed UTF-8 BOM (EF BB BF) from file start
• Replaced malformed emoji sequences with ASCII markers:
  • ✅ → [OK]
  • ⚠️ → [!]
  • ℹ️ → [i]
  • 🔍📖🔒 → [*]

The file now contains only valid ASCII characters and parses correctly.
